After driving vehicle on highway (30+ minutes at 65+ mph), exiting highway on exit ramp and coming to a stop (at stop sign or traffic light), the engine will sometimes stall and shut off. Immediately thereafter, vehicle can be restarted and driven. There are no other symptoms, abnormal sounds, vibrations, etc.
I thought problem might be caused by vapor lock. However, Hyundai dealer service center checked fuel pump, fuel lines and vacuum hoses, etc. but can not duplicate, identify or repair problem. Any suggestions???
