Same here. I'm getting really frustrated.
I've noticed that it happens when a player kicks the ball out of bounds over or around the goal and the goalie then has to line up for a goal kick. Right then it happens if you swing the remote and try and boot it. Really sucks and ruins a very enjoyable game.
I've found that if I just tap a pass out real quick with the A button that it often doesn't do it. It's almost as if the detailed graphics at that point ( the most detailed and moving of the game ) lock it up and cause a connection problem.
Where this really sucks is there are some wussy clowns that know it exists and try to get a quick first goal and then boot it way out of bounds repeatedly until the game locks up and ends. You'll get screwed and they'll force the loss on you no matter how long the game is !!!
Someone please tell me how to fix this or what can be done ?? REALLY LAME.
