breaks and engine cut, all code lights when on

If the engine dies you get 1 maybe 2 brake applications before it goes into hard manual brakes, so pedal effort is greatly increased, so gas pedal also will no longer work. All of the engine warning lights should have turned on at that time. So if it happens again you will need to find out why from your favorite shop.
