My daughter has a 2001 Dodge Neon. It sporadically just dies while driving. It doesn't ever seem to die if you just let it sit and idle. When it dies the speedometer goes to zero but the radio, lights, and other electrical continues to work. When you try starting it the engine cranks just fine but never catches. If you turn off the ignition and wait awhile it will start and seems to run just fine. When trying to start it sometimes it will start after 2 minutes and sometimes you just keep trying and it takes 15 minutes.
We have taken it to two mechanics and they have had the problem occur but only while driving, so they can't figure out what is going on. They said there were no codes being put out. They have determined that the fuel pressure when trying to start it after it dies is 48psi so it isn't a fuel problem.
It seems to happen when it shifts gears, it is an automatic, but it is real hard to tell if this is a symptom or related to the cause.
Does anyone have any ideas? The car is not reliable enough to use but two different mechanics have just told us "we can't find the problem".

Humm. It would be nice to know if you have spark while it's down. Coils don't like heat and can be tricky when they pull this trick (which is not funny)
Since you said two mechanics already have looked at it I would think they would have ruled out "no spark". Just an idea that a coil can do this and not throw a code to help if it starts working again. Makes you wish it would just stay broken! Then it could be tested. Good luck,

Resolved
The problem has been resolved. It turns out that the main wiring hardness somehow got caught was rubbed such that 8 wires had become exposed to each other. They would "randomly" short - more often when going the engine was working hard causing the engine to stop. After sitting the harness would "settle" and the wires would separate enough to "un-short". The wiring harness was removed and the wires spliced and reinsulated. The labor was about $700. Bad but it could have been worse - a new wiring harness is over $2000 just for the harness.
