The belt falls off because the belt tensioner bearing goes bad or you have broken accessory brackets. Sight the belt alignment through it routing and see if you can see which pulley is off. Also is the belt making noise while the engine is running. Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. Check out the images (below). Please let us know what happens.
