Your Corsica is most likely telling you it wants a new fuel pump. This can be verified by testing fuel pressure and volume. The fuel pump connector and ground should be inspected as well. A certified technician, such as one from YourMechanic, can come to your car's location to diagnose your stalling issue and replace your fuel pump if necessary.
