engine dies while driving

I have a 2003 Crew Cab 4X4 with a 7.3. When cruising down the road the engine will die. Sometimes it will come right back, but sometimes I have to pull over and turn off the ignition and restart it. Any ideas?

Without more information, history or symptoms I'd guess a faulty CPS. If you still have the factory CPS it is currently under recall. If not they're less than $30 at Ford (don't buy from the auto parts store).

A link on how to change is here: http://guzzle.rbmicro.com/cps.html

I agree with Chris, CPS.

Thanks for the response. The truck has 73,000 miles and the CPS has never been changed. I thought, from what I had read and heard in the past, that this might be the problem. I have a spare CPS, but I did not want to change it without being pretty sure this was the problem.

If your spare is black and not grey, i would let the dealer replace the cps with the new design grey one.. no charge .. on a recall..
