Sounds really similar to the problem I was having only much worse since it happens far more frequently, from your description. I may have been where you are now had I not taken any action as it was happening after about 1-2 hours of use. From what I understand since the heatsinks aren't held close enough to the chips, the CPU/GPU are allowed to get far hotter than they should and start to vibrate which causes the freeze. Get them hotter and you'll get the Red Ring of Death (3 red LEDs) which means they've lost connection with the motherboard.

If you're not into tearing apart next-gen consoles I'd check the documentation that came with your xbox, see if your warranty is still good. Then give Microsoft a call and see if they'll fix it/how much it'll cost you and go from there.
