GPU lost after sometime of using it

The GPU stops responding.
Running nvidia-smi I get the error “Unable to determine the device handle for GPU 0000:03:00.0: GPU is lost. Reboot the system to recover this GPU”.

I suspect is a matter of power supply, but i don’t understand the bug report (attached in the drive link). Can someone confirm it?

Thank you very much
