Ok,one common failure I have seen with these vehicles with this concern is a faulty crankshaft position sensor located just behind the crankshaft pulley.

These sensors will cause the engine to stall like this and in some cases won't restart for a few minutes and in others may restart right away.

This sounds like what could be at fault on your vehicle here and may need replaced.

This is the most common cause for this failure.

The sensor nomally costs around 100 dollars and requires a puller to remove the pulley to replace it.

The labor charge is usually around 1 hour.

I hope this helped if you need anything else let me know,thanks Pete!
