Shuts of while driving and will not start for twenty minutes

Hi,

Do you actually hear a click?

The first thing that comes to mind is a bad crankshaft position sensor. When they start to go bad, heat affects them. When it shuts the engine down, spark is lost to the plugs.

Take a look through this link and let me know if it seems to mirror what you are experiencing:

If it does, I need you to either check for spark when the engine won't start, or using a live data scan tool, check for an RPM signal.

Here is a link that shows how to check for spark:

If you determine the sensor is bad, here is a link that shows in general how one is replaced:

Here are the directions specific to your vehicle. The attached pic correlates with the directions.
