Sounds like a bad alternator. If the alternator fails the engine will continue to run off the battery until it's dead. Once the battery is dead and the alternator is not working there's no power for the ignition system so the engine stops. By leaving jumper cables on you're actually using the other vehicle's electric system to run your engine. HTH. -Jim
