So i have an issue where after i drive somewhere and my jeep get gets up to temperature, when i shut it off for a few minutes it won't start. It will fire up and immediately sputter out. It seems like once it's cooled down a bit it starts back up just fine. I've actually made up wires so that i can hook the cooling fan directly to the b battery for a few minutes to cool it so it starts right up. I'm looking for any insight on what could possibly be causing this.
