This would also be my first guess.

Five years ago I had an nmve in an intel nuc that would sometimes "go to sleep", here's the thread

@imp helpfully suggested running "nvmecontrol logpage -p 2 nvme0" which showed mine was hot (60° C/140° F)! I adjusted the fan settings in the bios and have never had an issue since.


oh interesting, i'll run that next time it locks up. the box is well ventilated, but that's not to say its not overheating. right now its at:
Temperature:                    314 K, 40.85 C, 105.53 F

nvemecontrol doesn't list any errors or warnings though:
Media errors:                   0
No. error info log entries:     0
Warning Temp Composite Time:    0
Error Temp Composite Time:      0

thanks for the tip!
