1993 Blazer stalling intermittently

Hi,

I have a 1993 Blazer that was tuned up last year. It normally runs very smooth but twice in the past week it has stalled. After restarting, it idles rough for 30 seconds and then it is fine to drive again. Once it stalled while I first took off to drive it and the other time it stalled when I was driving 55 mph

I appreciate any help someone would give

Thank you,

Vinnie

Is this a k1500 blazer or s10? What's the litre size of engine? Any applicable trouble codes? Intermittent issues can be hard to track. You have to test when problem is ongoing. The tune-up consisted of what?

I had a 93 S10 4.3L that had a continuing problem with the Distibutor Module. It would get hot and the engine would die, cool off, and then it would re-start.
