Some weeks ago, my vehicle started failing and I hope you can give me a hand. After driving for 30 minutes or so, and stopping at a traffic light, the engine stalls and it is really hard to start it again. I need to wait for a long time until it cools down. Once, it stalled when lowering the electric window, being stopped at a traffic light. I've already checked the coil, spark plugs and injectors. The car was scanned but no failure was indicated, except for a low electric current consumption. I really do not know what might be happening.
