That didn't work. It shut off again today. Any other suggestions by chance? Would a power steering pump or anything like that cause this? Thanks for your help, too.

Crank Position Sensor is the other likely culprit but usually that will generate a code.

I would think that it would throw the belt before an engine-mounted accessory was enough to stall the engine, with a working IAC valve that is.

We didn't change the crank sensor. We did go over all the vacuum lines and plug ins and found my pcm was loose from the body. So far, since we tightened it down, it has not shut off. Fingers crossed! Thanks for your suggestions.

Until next time!!
