Driving approx. 5 minutes when car warning lights (check engine) and all dash warning lights came on immediately there after, car engine shuts off. Car engine would turn on when started but as soon as you engage the transmission by moving from park to drive, and press the gas pedal, car engine would again cut off. At no other time prior to this did check engine light come on, oil light, or water temperature gage show any malfunction. The professional mechanic that checked my car and ran diagnostic testing can't find any problems. He says he has driven the car but, can't guarantee this will not happen again.
