1996 Chrysler Concorde stalling

The Check Engine light means the Engine Computer detected a problem, set a diagnostic fault code, and turned the light on to tell you. It's important now to not disconnect the battery or let it run dead until that code has been read and recorded. The most likely suspect is a failing camshaft position sensor. If it is failing, you won't have spark when it doesn't start.

If the fuel pump fails the engine will stall within a few seconds. The injectors need fuel pressure to operate and the fuel pump supplies that pressure.

It is extremely rare for a Chrysler fuel pump to fail once it has started up and is running. They almost always fail by failing to start up when starting the engine, so the car leaves you stranded in the driveway or parking lot. GM fuel pump, by contrast, usually fail while you're driving, leaving you coasting to the side of the highway in the middle of nowhere.

You still didn't tell me what the diagnostic fault code number is or whether or not you have spark when the problem occurs, but the fuel pump and pressure are not monitored, so problems with the pump won't turn on the Check Engine light.

All right! One in a row! Happy to hear you solved it.
