PO 351 NO ACCELORATION AND RUNS RICH

Question

We have changed computer, crank and cam sensors, distributor cap, rotor button, ignition coil and plug wires. Jeep sets overnight starts, runs good for about 10-20 seconds, then it starts running rich/misfiring....and dies. Sometimes it won't start back up, other times we can feather it and it will run for a little bit but not long. It was running okay before we changed the oil pan, rear main and timing chain.
