MacBook Pro seems to be able to avoid random shutdowns when disconnected from network or when running is Safe Boot mode.

This implies you most likely have an issue with third party software that is installed. Run the third party app EtreCheck and post the complete report here so we can examine it for clues.

Thanks for your reply, HWTech,

At the time you wrote your reply, I had only just wiped Macintosh SSD and reinstalled Monterey. There were no third-party applications installed. The first app I installed was EtreCheck.

Thanks for confirming. You have proven there is a hardware issue of some sort. If you had no external devices connected, then the hardware fault must be with the Mac itself which means the computer will need to be repaired.

The best way to convince Apple of a hardware fault is by showing Apple the Kernel Panics occur with a clean install of macOS without any third party applications being installed.

Personally I would not spend any money on repairs for any 2016-2020 Intel Mac with USB-C ports for multiple reasons. The money spent on repairs is better put towards a new laptop. The M-series Macs are such an improvement over the 2016-2020 Intel Macs with USB-C ports and M-series Macs are the future for Apple. Besides I think the 2016 model is now considered "Obsolete" by Apple so Apple will no longer repair it which makes your decision so much easier.
