It's not going to be the entire crankshaft itself. I suppose someone already pointed you in the direction of the cranshaft, so I will have to stay in that general area having not knowing the symtoms and problem areas of your car.
Background: The Chrysler Concorde and 300M have a bad problem when they get into med-high mileage (60,000+). Stuff starts to break. They were build kinda crappy.
Anyways, it's probably going to be a pilot bearing or a thrust bearing in your block, that supports your spinning crankshaft, that will fail. If the crankshaft was "bad" the engine wouldn't run for a second, and the starter wouldn't be able to even crank it.

Need more info. If you had a bad crank there would be an awful ammount of noise. If one of the bearing surfaces is galled the engine would get extremely hot and would shut off. With this though you would probably never be able to start it again because of the components friction welding themselves together. With no noise or extreme heat I cannot see how someone could diagnose your problem. If it runs for a short period of time and then shuts off I would have to look toward a clogged fuel filter or an electrical (electronic) problem, not the crank shaft itself.

sounds like a crank sensor or a ignition control module

yes, but i doubt that is your problem, and if it is i bet its not the only thing wrong with your 300c, does it have good clean gas in it?
