I find Go Pros cameras can handle heat. All day heat in the sun running continuously. Stopages seem to be mostly due to poor memory cards. I have tried many brands and sometimes certain brands are liked better than others even if they spec out the same.

I have had two and three cameras running side by side with the same brand and spec of cards. Sometimes one camera will stop and shut down. I will swap out a known good card and if it continues send it back under warranty.

Poor cards tend to bottleneck throughput and generate more heat.

The Samsung Evo V30 cards as well as the Lexar Professional 1066x Silvers are really good performers.

The newer the camera (higher model numbers) do run warmer than the older 3, 4 and 5s. If you are getting a temperature shutdown under water I would make a warranty claim. All generations of cameras have reported heat issues. Cards resolve most of them but when you pack all that temperature emitting tech into a little box something is bound to happen, nature of the device.
