Lights Out

[riverfalls57]

I am not an umpire but I observed an interesting situation at a game (12year olds) I was watching last week. Runner on second with one out, the batter hits the ball on the ground between second and third, neither the 3rd baseman nor the SS can make a play on the ball. Just as the ball reaches the outfield grass the lights go out (it was 9:30) making it almost impossible to see. The outfielder can't find the ball and both runners score. The Umpire never called for time. After the lights came back on (about 20 minutes later) the runner on second (who was between second and third when the field went dark) was allowed to score and the batter was put on second base. I have never seen a situation like this and wondered what the correct procedure is. Thanks for your time.
