No this is not normal with this lens. With intermittent symptoms such as this always try the quickest and cheapest fixes first...cleans contacts on lens, flip switch from A to M and back to A again (sometimes these switches are hit accidentally in the course of use), turn camera off, dismount and remount lens again, firmware check - make sure up to date on both camera and lens. If all that checks and it still is flaky, then send it off to Nikon!
Thanks, tried all that so off to Nikon it is.
