It will turn over and start, but shuts off after twenty seconds of running. I changed the fuel pump, filter, line, the relay switch, fuses and oil pressure socket. I am clueless what to do next.

If I can add in here, it could be the crankshaft angle sensor or the fuel pump, here are some guides to help.
