My D850 does something that I don't understand. I was taking family pics out in my yard this weekend and while several photos looked normal, then, without any change in my camera setup, it would take the next few pics totally blown out (white out). It has done this before. I can usually recover the darker objects in Lightroom but the whiteout objects in the photo are gone. Then it will go back to taking normal photos as one expects.
...bracketing setting.

I now have food for thought from your suggestions. I would like to upload two pics, one normal and one abnormal to show. Not finding such link yet.
The posted pics are useful but lack the Exif for a decent investigation of whats going on so we can't see if bracketing has come into play.
But, looking at the histograms of both images there are considerable 'spikes' that suggest some serious PP may have been done to both.
The values of the 'blown' (used loosely) area of the second shot show values in the 220s, suggesting attempted recovery of a blown area has been done.
Interesting.

Lighting is everything. If you make the choice to shoot under a tree (deep shade) and the background is brightly lit, you have no other choice but to give priority to the background and lower your exposure to avoid the blow out, and post process the main subjects to a brighter level, or you can take two exposures, one for the background, and the other for the subjects, and merge the two in post processing, or set up a couple of bright monolights and softboxes or large umbrellas fairly close to the subjects to provide your own light, and hope that your light is brighter than the really bright sun. Or you can choose a better setting/time of day, etc.
There is nothing wrong with the camera.

OK, first things first, do a reboot of the camera. Look at the top of your camera and find two buttons that have a green dot next to them. Turn your camera on and hold down both buttons with the green dot next to them at the same time for 10 seconds. This resets all of the settings on your camera.
If the problem persists, call Nikon at 1-800-645-6687. Ask for technical support.
Good luck and keep on shooting until the end.

You haven't ever said what metering mode you are using, but it is clear that in the second photo (which appears to be a crop from a larger inage) the exposure is heavily influenced by the black shirt that the gentleman in the center is wearing. The exposure of all three of the guys is pretty close to correct. The background, which is in direct sunlight, is at least 3 or 4 stops lighter.
Gene is correct. There is nothing wrong with your D850. You have just asked it to do something that no camera will be able to do.
That said, if you are willing to do some post processing, this would be a perfect time to use highlight weighted metering, as suggested earlier, and bring up the shadow detail from your raw file in post processing. The D850 has plenty of dynamic range to do that. Some other cameras might not. Merging two or three bracketed exposures via HDR processing might also work, but in my experience, doing so with the D850 might not be as easy as the other option. The D850 also has some other built-in capabilities to deal with situations like this, but I haven't used them very much yet.
The camera appears to have done exactly what you asked it to do here. It just wasn't what you really wanted.

I have accidently turned on or left the bracketing feature on and this would happen. 1st and 2nd photo might be fine but the next one or so would be blown out depending on the settings.
Me too

Looks like spot metering to me. The second shot would meter the black shirt overexposing everything else.

Thank you all so much for your comments. I will seriously take them into consideration on my next shoot.

I notice that in the second photo the blue shirt of the gentleman on the right is now blown out to a white shirt as well. I know with my D800 changing the point of aim where I click on my BBF will change the metering of the camera. That would be with spot metering as others have posted.

What did you focus on in each pic? Spot metering with your focus point on the black shirt in one pic and the white shirt in the other would give you varying results like this. That would be my WAG for the day.

You may have a shutter issue. I had this happen to my D4 but it was after if made a short drop to the floor so I knew why but got the exact same results.
If it's under warranty you might want to take it in.

One of the easiest ways to check your shooting data is to view the image taken in NikonView Nx-i. It is all listed in one of the four right hand panels--File and Camera Info; XMP/IMPT info; Adjustments; Histogram. It is free. Just download it from NikonUSA Download center.
Regarding your problem, It could be that spot metering was set instead of Matrix Metering.

I had similar problem and actually I caused it. Make sure your menu B4 setting is off...or that you don't touch or brush against the rear adjustment wheel if you've put the setting "on"!
