make sure the battery itself isn't damaged. one of the top posts could have been hit with something causing them to break loose/short out and when you wiggle them or hit a bump it may cause a complete break in the circuit.

then again, it SHOULD stay running if the car makes it on anyway. Also, make sure the grounds are good and cables aren't touching anything they shouldn't, and that the alternator plug / power line post isnt' loose.
