Jeep dies on Interstate - cools and restarts???!!
Hi guys,
We have a 1986 CJ7, with a 1991 4.0 fuel injected engine. It runs super sweet almost all of the time. It starts easily, is smooth at idle and acceleration, and just generally is a great motor. However, when I try to go more than an hour away from the house by interstate, after a while it just dies as if it is out of fuel. It will not restart until it has cooled down for 10-15 minutes, then it will run perfectly for another 30 min or so until it dies again. Something is obviously overheating, but what? I do notice that the external fuel pump we use sounds unusually loud during these episodes as if it is having a hard time getting fuel, but unless it has died, it runs great. Any ideas? Thanks!
Joe
