2008 kia optima stalls while in motion. Vehicle will shut itself off. It is as if someone reaches over and turns the key off. It has happened with the car standing still and with the car in motion. Stalling usually occurs within first few minutes of operation and with hot outdoor temperatures. First visit to kia resulted in replaced fuel tank (codes for bad roll over valve). Problem went away for about a year then came back. Car has been in the shop 4 times over the last month and a half.
