The only cameras I know of that can do this are made by Panasonic. Lumix GH5 is your best bet. Dual card slots, NO 30-minute time limit, NO overheating, GREAT video and audio quality, very good low light performance and surprisingly great stills.
You would need the battery eliminator (AC adapter, OR a battery grip and multiple charged batteries.
While you may or may not have a 30 minute time limit, you definitely still have a 4 gigabyte file size limit. I suspect like many other modern cameras, it automatically starts a new file when the 4 gigabyte file size limit is reached.
