The Koup, my avatar, is driven from Waxahachie, Texas to Port Aransas, Texas on Friday - no problems. 6 hour trip each way. Return driving on I-35 at 75 mph, speed limit, when the engine quits. Engine light is on. pulled over to the shoulder. after 10-15 minutes the car will start. I drive off. The engine stalls and quits again after several miles. Engine light is on. I pull over for a longer time while I arrange towing with KIA road service and visit with a Texas Highway Patrolman who is checking on me. I start the car again, engine light is off, I cancel the tow and drive home. Car makes it home. The last time a car acted this way, a VW Jetta, it was a fuel pump trying to fail. It did thin a few times and then quit for good. The car is a 2014 Koup SX I bought new in January, 11, 450 miles. Is this a fuel pump or what? Anybody else have such an adventure?
