'05 Excursion w/ 6.0 just dies in traffic

[jbarnhill]

My '05 Excursion has recently developed an intermittent problem where it just dies. It always happens after driving for an hour or more so engine is at operating speed. It always is when I have been at highway speed for a while and then hit rush hour stop and go traffic and am feathering the 'gas peddle' or tapping the breaks or am getting to my destination and have gotten off the highway and am slowing at a traffic light to make a turn. The engine just flat dies; no coughing, no sputtering, it's just like I turned off the key. So far, the engine has always easily restarted. I can just put it into neutral, hit the ignition, and I'm going again.

I've had it into the dealer 3 times now. The first time, they found an EGR code and replaced the EGR. Did not fix the problem. The next two times I took it to the dealer, there were no codes. They can't duplicate the problem. Ford does not recognize the problem.

This all started at about 36,000 miles. Now I have 40,000 miles on it.

Any ideas?

Im not sure on ford wiring but international trucks with this engine had the same problems. Somtimes it would set a code and somtimes not. Check all power and ground connections to the computer. International actually had a recall to cut out and hard wire all these connections. Hope this helps

we have a 7.3 at work that had the same problem. It would just die in the middle of traffic while i was towing a huge trailer! It would start right back up though. They replaced either the crank position sensor or cam position sensor it hasn't done it since! Said it was a common problem and if it hasn't happened yet to go buy one and stick it in the glove box because it will happen! hope this helps

that's only on 7.3 liters, I think.

Try the crank position sensor, see where that takes you. Its like a hundred dollar part.
