When the problem occurs, use a gage and check fuel pressure. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. The gray wire at the pump connector is voltage for the pump motor. The purple wire is voltage for the fuel gage sending unit. Engine cranking, take a voltage reading across battery posts, the reading at the gray wire, pump connector, engine cranking, won't be any higher. Right now, I don't care about the initial prime.
