Hi,

It could be a few things. When it stalls, do you have to wait for it to cool for some time before it will restart? If so, that is likely related to the crankshaft position sensor. They fail when hot when they are going bad.

Take a look through this link to see if it mirrors what you experience:

Also, it could be fuel-related or something with the electronics. If the check engine light stays on when the engine is running, scan the computer for codes. Here is a video showing how it's done:

I realize you may not own a scanner. However, most parts stores will do it free of charge. If you have it done, let me know what codes are found.

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
