96 Caravan stalls after highway driving

Sounds like a fuel pump problem to me, more then likely its the original one in the tank. You may have a hard time finding someone that will drive it for that long to get it to act up and a fuel pressure test will more then likely show good if it is tested while it isn't acting up. My other guess is that there probably isn't a check engine lite on because the fuel pump wont set a fault.

I'm with Glenn. This sounds just how my 96 GV acted when the fuel pump was failing. The dealer finally installed a fuel rail pressure gage, taped it to the windshield and then drove it for a few days until it acted up with them. It took nearly eight months and four visits to the dealer (two via tow truck) to isolate the problem.

FWIW, I have a 92 2.5 Dodge Shadow that gave the same symptoms. Mechanic guessed the fuel pump, but then checked the codes using his machine. It was the oxygen sensor going bad, and after the engine had run for awhile, the computer would try to lean out the mixture, untill the vehicle became undriveable. Let it sit for awhile, and all would be fine for an hour or two. Replaced the sensor, its run fine ever since.

Tell me Noman, have you -ever- had that happen to you or are you just pulling this great story out your ass?
