Hi,

If the vehicle stalls and won't restart until it cools for a while, chances are the problem is related to the crankshaft position sensor. When this sensor starts to fail, heat will have an adverse effect on it causing the engine to stall. Once it cools, it will work again.

Do me a favor. Take a look through this link and let me know if it seems to mirror what you experience.

If this seems like a possibility, then do this. When the engine won't restart, watch the tachometer when cranking the engine. It should move a little, or get a live data scan tool and check for an RPM signal. If there isn't one, it is likely a bad sensor.

Here is a link that shows in general how one is replaced:

If you look at the attachments below, I provided the directions specific to your vehicle for sensor replacement.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
