I might suspect hardware...

You run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.

Use Apple Diagnostics to test your Mac

Kernel Panics are predominately caused by hardware faults or faulty third-party kernel extensions.

Learn what to do if your computer restarts or shuts down unexpectedly, or you get a message that your computer restarted or shut down because of a problem.
