If the belt is staying under proper tension, there is a pulley that is turned or tipped. That can be due to a component that isn't mounted squarely or a component with a worn bearing. That makes the belt slide across that pulley or the one right after it as it goes around it. If you can get your head in there, sight down along all the pulleys and look for one where the edge of the belt is peeking out as little as 1/16" compared to where it goes around all the other pulleys.
