Hi, and welcome to FineTunedMac.

Sorry to hear about your problem.

The first thing I'd try is booting from a clone or other external bootable volume, and I'd next run Apple Hardware Test which, depending upon which MBP you've got, is either on a disk or on your machine.

Please let us know how you make out in both respects.

You may get some insight from this thread.

hardware test time. specifically, check ram

In which case, check the box to run the extended test.
