Its a 21 f3s, 900 miles on it, 1/2 tank of gas, about 100 miles into a ride, as flat of ground as you can find in Ky, mild acceleration. Wife said it started downshifting, she gave it more throttle and it died. Dash was still working, didn't hit the thumb switch. Motor wouldn't turn over until the brake pedal was pressed. Fired right up and did fine the next hour home. No codes no check engine light.
