At 70 MPH the engine turns off as if a switch was flipped. This has happened multiple times, always on the interstate and always with cruise control on and active. It occurs more frequently in the hot summer months (110+ f). The warning light for the throttle control circuit sometimes illuminates. While still moving, selecting neutral, turning the ignition off and then back on allows the engine to restart. This can occur as frequently as every 60 miles, but the average occurrence would be around 150 miles.
