Sounds like your ignition switch is intermittently beginning to fail, Have a tech check it with a meter, here's a site that has them much cheaper than the dealer http://bit.ly/hUQYR

SAME THING HAPPENED TO ME!!! I had to leave it with my mechanic for over a week for him to figure it out--but it was a sensor that was telling the car it was hot when it really wasn't. tried bunch of other things that didn't work, but it hasn't happened again since replacing the sensor.
