I was stopped at the top of the hill on a private road. when i took my foot off the brake and pressed the accelerator, nothing happened. the car began to roll backwards and i pressed down on the brake. the brake was very weak and it took 50-60 feet and all of my pressure on the brake pedal to bring the car to a stop. after i stopped, i realized that the engine had turned off and the ignition was int he off position. i rotated the key in the ignition back to the start position to start the engine. i continued back up the hill normally after the engine was started. luckily, there were no cars behind me on the hill or they would've been hit.
