Skyrim game problems?

It's not that I am stuck anywhere or cannot find some trainer, I am nearing the end of the Thieves' Guild quests (or so I think), and I am in the Falmer cave place hunting down you-know-who (don't want to give away spoilers), and my game has become insanely choppy. I am playing on an xbox360, so it's not PC component issues or anything. It has happened twice now, it starts off like when you first spawn on a CoD game, but then it gets extremely bad to the point where it's a new frame every 2 or 3 seconds.

My xbox is pretty new, it doesn't happen on any other games, and these are the first times it has happened (in the caves), is it just a game glitch (like when the game freezes during the Dark Brotherhood quests, when you are in the Nightmother's coffin), or has this not happened to anyone else?



I have tried playing on the disc (which is not scratched) and the installed version, the problem occurs on both. What I have to do to get it to stop is Save %26gt; Power Off xBox %26gt; Restart, which makes me think that my xbox is overheating, but nothing is different in the heat, or sound of it from playing skyrim to watching netflix, etc.



Any ideas of why this is happening? Is this common? And what is the best flavor of ice cream?
