Hello. Welcome to Just Answer. Please allow me to assist you. Sadly, the C1223 and 1224 codes do not have anything to do with the engine shutting off. These are ABS codes. The C1241 code my be possible, as this code relates to electrical power in the vehicle. A C1241 code is set when the electrical power in the vehicle is below 10 volts. The computer in this car shuts off when electrical power available (from the alternator) is less than 10 volts. So, what this sounds like to me is your alternator is not producing enough voltage to cause the computer to run the fuel injection and spark systems. Most likely, you will find after a alternator test is your alternator is not producing the specified 14.4 volts at all times. This sounds to me like you are going to be looking at replacing the alternator.
