There have been a couple of incidents where I will be driving and my car suddenly jolts and coasts to a stop. It seems as though the car is being placed in neutral while I am driving because when I press on the gas. It will just rev the engine. The check engine light will turn on as well. I typically turn off and on the car and the car will then work just fine. These incidents seem to happen when I am driving on a city street.
