Vaccuum leak. Check em baby.

or it a motor sensor cause of the 94 and up it does that when one of the sensor goes out

Don't think it's a vacuum leak, but take AusTexRex's advice and check anyway, cause you can always find a bad hose. How long does it run before it shuts down on its own? And what year is it? or did I miss that?
