Agree! You sure that the gas cap wasn't loose. It happens almost everytime my wife puts gas in my Brub or her rice-burning Nissen. I have a code reader, so I just plug it in an do a reset. I think you can reset by disconnecting the battery for a few minutes, but then you have to reset the clock etc.
