Unfortunately for intermitent problems a technician would require more diagnostic time in order to reproduce the symptom. My first guess would be where wire connections are not clean and tight. For instance, check to make sure ground connections are clean and tight. It may not be the problem, but common. You could also have sensors/actuators that are probably going bad (could be defective components). This is where having a scan tool or a repair shop with scan tool that not only pull trouble codes, but can read values from sensor while driving the car. If you know when it occurs say, cold startup and after engine reaches normal operating temperatures does the engine stall. I would say the more information you have, as to if there are specific conditions when the engine would stall, the easier it is for technician to diagnose the problem. Hopefully this is a good starting point to help find specifically where the source of problem is occuing.

There is a few possibilities. You could have the Crank Position Sensor going out which would be the worst of it. Cheap part but labor may cost a lot. I was having the same problem and I noticed my coil packs had rust on them where the spark plug wires connect. I cleaned them last Saturday and haven't had a problem since. Be sure to check your fuel and spark system. For it to just shut off your losing one of those. Most likely its the spark.

The same thing happened on my 98 grand prix, it was just a loose ground wire from the battery.

This happened to me. It was the Evap sensor located on the intake. No problems now. Inexpensive and easy to replace. No more shut offs.
