You are right about that TSB (not sure about number either), but that referred to the shimmy that you are talking about and not the system going into off. Mine did not shimmy at all. It was off then on then hard off. Still definitely worth bugging the dealer everytime it happens and not cycling the ignition.
True, but, it might not be a bad idea to run the TSB as I had heard that some experienced the "shimmy" while others had different problems. Wouldn't hurt to check that avenue....
