Run rough and shuts off

Hi Thomas and thanks for using 2CarPros.com.

I have to be honest. What you described sounds like a crankshaft position sensor going bad. Take a look at this link.

Now, with that being said, what to do is this. If the engine stalls and refuses to start for a period of time, check to see if there is spark to the plugs. Here is a link which describes how it is done:

If by chance you have or have access to a scanner which provides live data, you could check if there is a signal from the sensor when you have trouble or if the signal itself is erratic. If you find that is the problem, the sensor is located near the crankshaft pulley (harmonic balancer) at the front of the engine. I have attached a picture of its location to better help you.

If you have questions or need additional help, let me know. Regardless, if you can, let me know what you find.

Take care,
Joe
