7.3 starts, runs, then dies after a couple minutes

[flytimothy]

I have a 7.3 2003 F350 Auto that runs fine, then all of a sudden dies. Gauges go flatline. No strange noises or sputtering. Just dies. It seems as if I wait a few minutes I can try again and it starts. It turns over fine so the batteries seem good. Wierd part is the day before this started happening I took it on a 200 mile trip with no problems. I can say the truck sat more than usual this summer due to the high fuel costs. Could this be the CPS or a fuel pump or some kind of computer part? Alternator?

Please help! Had to get towed home last time over 60 miles.

I replaced the fuel filter with no change so far.

Have you had the CPS Recall done on it yet? You can call Ford to schedule it - Free.

My truck was doing something similar only sometimes it would shut off while I was driving. Since the CPS was replaced, no problems.

Thanks everyone! I had the CPS recall done yesterday. So far so good!

Have you had any recent problems with it shutting off?

This happened to me last night. I started my truck and started driving down the road about a mile later. Truck dies completely and then after pulling over it would start back up, weird......

I haven't driven it much yet. It didn't do it again yet. I had to wait for my AAA 100mile free towing to kick in in case it happened again .

At least the recall is free so I would give it a shot. It needs to be done anyway. Those are the same exact symptoms I had.

when yours died would everything shut off? Like the radio. And then it would come back on?

[flytimothy]

I know all the gauges went dead. I didn't have the radio on so I am not sure about that. I do remember thinking it was like someone hit the kill switch.

Was it raining or snowing prior to this problem, if so I might have an idea for all having this problem. I recently had a similar problem during and after a snow storm, I took my truck into the local dealership and they narrowed it down the a IDM issue, either a connection or a damaged IDM, the told me there is not a test for the IDM and it would cost about a $1,000 for a new one. I told them let me think about it and drove it home, from there I took apart the drivers side inner fender and removed the IDM, after disconnecting I notice a small amount of moisture and a burnt mark next to the high voltage prong, I cleaned up the connectors and took a heat gun, placed on cool and dried the IDM connectors. I then applied a generous amount of di-electric grease to both ends of the connector and after reconnection I applied a coat of marine grade waterproof silicone spray to the connector. After putting everything back together I have put a couple hundred miles on and it has not had a problem.
Hope this helps
