What is your question?

Almost everytime I drive my car at some point while I'm slowing down or at a complete stop, my engine will stall, than I will start it right back up again. I had an auto specialist scan it, couldnt get a reading. My car is literally at a shop right now the guy just test drove it, it didnt happen so he doesnt know what the problem is. Any thoughts? Check engine light comes on than car stalls, unless I hit the gas to prevent it from stalling...
