I just recently noticed my obd system gave me codes that indicate a faulty quad driver modual and cylinder select error, and my car has been driving fine except the motor cuts out ramdomly every once in a while, does this sound like a faulty ecu or maybe just a sensor?

Ok, so does my ecm need replaced or maybe just reprogrammed? And which problem do you think causes the cutting out?
