Car accelerated as I tried to stop. Then when I tried to go, I pressed the gas and it would not go but the rpm's went really high. Then the car died and I had to wait a few minutes to turn it back on. 2nd incident- I was driving on a busy road during rush hour and tried to stop at a stop light but the car accelerated so I had to keep breaking but the car would not stop accelerating so I turned the car off. When I tried to turn the car back on, nothing worked (had no power at all therefor I could not turn on my hazards to signal to people that my car was stalled). I waited then tried to turn it on again and it turned on but was still accelerating only I was in park so it did not go anywhere. I turned the engine off but did not turn the car off so I could turn hazards on. I waited several minutes then tried again and was able to pull off the road.
