Randomly during games i stop being able to control my champion???

I am playing the game as usual, when randomly i will stop being able to control my champion, if the last thing i did was rightclick an enemy, i will just keep autoing them and wont be able to run away or do anything. i cant ping, cant move away, cant use abilites, nothing. i dont think its a dc either because i can clearly see everything that is happening in real time, but cant do anything. i dont know why this happens, and its cost me 2 games straight and just started having this problem after 11 games,
