RUNS THEN WILL CRANK NOT START THEN RUN FINE A FEW HOURS LATER

1996 Ford Explorer • 219,000 miles

1996 ford explorer 4.0L V6 pushrod engine. I am pretty sure it is the cam sensor but since this seems to require pulling the intake I want to be sure. The fuel pump will stop running and the vehicle will die then a few hours later it will start right up only to die again shortly to a few days later. I have ran an OBD2 scan with no codes. I have pulled the pump, since this is what I originally thought was wrong the first time it happened put power to it and it ran fine so I reistalled it and the vehicle fired right up then died again a few days later.

There should be no power to pump when the key is off, try disconnecting the fuel pupmp relay inthe power dist box if you still have power then you have a short someplace.
