2001 Chrysler Concorde engine stalls

When the problem occurs, are you saying the vehicle cranks good, but, won't start? Have you tried any basic tests? Have a helper crank it while you check for spark at the plugs. Listen for the fuel pump, when you turn the key on. Can you check for troublecodes? Some of the national brand auto stores will check codes for free.

I always check for codes, I don't care if the lite comes on or not.

If you can hear the fuel pump run at key on, that's good as far as it goes. You need to check fuel pressure when the vehicle refuses to start.

When the vehicle refuses to start, did you check for spark at the plugs? When the problem occurs, if your missing fuel and spark, that leads in a direction. If you have good spark everywhere, when the problem occurs, then concentrate on the fuel system.
