Yes, I have seen games stopped, but to get site director involved and handle the situation not the umpire and it has never been anything to do with people yelling things to players. It has been fans getting into it with each other or one time a kid was walking around pointing a laser pointer at players. I have stopped a game to tell the coaches to handle their parents when f bombs started flying back and forth with threats being made, but never about people yelling instructions from the stands.
I have on 2 or 3 occasions put coaches back in the dugout, but they were actual coaches not spectators.
