After getting gas, once i got onto the highway, about 400 or so feet, my car started shaking violently and then my check engine light came on. i didn't know what was happening and my car was slowly stopping on its own accord. luckily i was able to get off on the nearby exit, my car slowing by itself as i drove. as i turned in to go to a gas station, my car stopped on its own completely, even when i tried to push on the gas. i turned the car off and waited about 5 minutes. after that time, i was able to start it up and my car turned on and no alert lights were on.i i was then able to drive on back roads to my house, with no further issues. please help me resolve this issue. i am terrified i am going to get in a car accident.
