It just might be that your 360 and/or its hard drive is giving up the ghost. As my original 20gb drive got closer to its end, it experienced more and more errors, in particular the one wherein pressing the power button on the 360 did nothing the first few times. I'd end up getting more disc-read errors, freezes, and crashes that required turning off the unit instead of exiting to dashboard or ejecting the disc.
And do you play other games much at all? If you only play New Vegas, I suggest clearing your system's cache for the game now and then (something like holding both bumpers and X + Y at the same time at the start up, look it up to be sure) or else play 3-5 other games in between sessions of New Vegas (your 360 cycles its game cache per 3 different games or something like that).
