While driving on a 40mph road, the engine spontaneously lost power - the power steering and brakes also ceased to function as a result. The radio and lights were still on. After guiding the stricken car to a safe area, I turned the engine back on and was able to drive as normal. The issue repeated roughly a week later at lower speed while going over a speed-hump in a shopping center parking lot. Note: the issue occurred following the addition of apartment and mail keys to the keyring. I separated the additional keys from the car's key following the second incident. The issue has not repeated since.

While the driver either attempted to stop at a light or stop sigh the brake pedal would almost touch the floor. This problem started about two weeks after the vehicle was purchased. The vehicle was involved in two accidents because of this problem.
