I know but I can't get it over that with it running. It's almost like the fuel pump shuts off while it's running, and right before it dies it turns on and then shuts off.

I have tried jumping it and it works but if you start it leaving it jumped does nothing, and for the oil pressure it has a single wire sensor, so it would not be switched, unless their is another one I do not know about.

I have found the problem! It was a ceramic resister that controls the fuel pump after start up it lowers the voltage to the pump so the pump lasts longer and it is not in any repair manuals, took 3 hrs of looking at online diagrams.
