I can't find that error code in any service books. Are you sure it's not just 2 numbers? Without taking any wild guesses your machine may be over heating and shutting down on thermal overload. Are the fans clear? Have you blown out the machine lately? Look close again at the error code. Here are the codes, 31, 32, 33, 34, 35, 37, 39, 43, 44, 47.
