While I was driving the car suddenly stopped sending gas when pressing the gas pedal and put the can a neutral mode. This was the second time this happened. Luckily the first time I was in my neighborhood going slow. The second time was in the middle of the night pitch black on a busy road. I was stranding the middle of the road and almost got hit. I was so fortunate a cop was driving by an helped. This has been extremely unsettling as I have a 1 year old. Luckily he was in the car but I can't imagine if I was driving with him on a highway.
