I was driving on the interstate and the vehicle was in cruise control. It acted as it was accelerating and then the cruise control quit and I lost speed. I regained speed and then it lurched again; the cruise control again went off. When I applied the brake to pull to the side of the road, the engine started to throttle up and accelerate, I had to brake harder to come to a full stop.
