Driving at 75 mph and went to pass someone. The engine kicked down a few years and the entire car shut off. No power brakes and no steering and steering locked up for about a second or two. During the time it was off the vehicle jerked hard like if the tires had locked up. After the couple seconds the vehicle turned back on and everything was normal and no check engine lights or anything to indicate a problem I was driving on the I-80 heading to reno.
