Here is the latest: replaced Fuel Pump Relay and the Oil Pressure Switch. Still no good. So it's not the MAP sensor, Pump relay, Oil Switch, and no codes have been thrown. I took off both the relay and the switch and put on jumper wires into the pigtails and I can get it to run fine. That leads me to believe that it is not a bad wire somewhere. If I let it warm up to operating temperature and then put the relay and switch back on then it works fine. As soon as it cools down, back to shutting off after two to five seconds.

My next, and scary thought, is the computer itself. What are the chances of that?
