Did a long drive today and then parked it for a bit. When I when to start it it started as normal but as i was driving it stalled and would not start again. This is the first time this happened. I can hear the fuel pump priming but every once in a while the pump squeals and this is the first time that I've heard that from my jeep. So it sat for a while and I got it to start again. As i was driving the same thing happened, it randomly died and would not start. If I let it sit for a while it usually will start and run for a limited time. Im thinking its the fuel pump or relay?
