Serpentine belt busted replaced and now loss of power when accelerating

What is your question?

My 2015 Nissan Altima S 2.5 started overheating, I started to pull over but before I was able to the serpentine belt busted. so I had it replaced we filled all the fluids. On my way home my car started overheating again i pulled over and allowed it to cool before I drove it again. I made it to the last stop light to my home when light turned green I accelerated and the car just lost total power. When driving feels like it's stuck in low gear? After thorough inspection of hoses we found a hose disconnected
