Ok got 96 Blazer V6 Vortec. Starts up fine runs smooth but then shuts down when run awhile. Won't start again until it completely cools down then will start and run again. Replaced all usual subjects(icm, coil and pick up coil/cam post. sens.) still does it> Anyone have any clues? thanks

 

Have you tested your fuel pressure during the no-start condition?

Are there any codes present?

 

No I haven't checked fuel press. I'll do that next and scan for codes. Thanx for your response. Keep you posted.
