Should be an engine to body ground somewhere, no? I would think APPS sensor too. How much fuel in tank when this happens? Could it be fuel slosh away from the pickup letting air into the line?? I would see if you can find the original fuel pick up and reinstall the Raptor. I have heard funny things from Draw Straws and the in tank pump. Change the gaskets on the lines at the fuel filter as someone may have reused an old one when they changed the fuel lines from the original pump???? Best of luck... Chris
