After lurking around for a while i noticed a pattern that if you run out of memory, then the game crashes. So after some help from some great people here I learned how to get rid of my space trash I got rid of 3 satellites, and all the space junk, and my game has not locked up since.
I went to the tracking station, and got rid of everything. I clicked on a item, then below it there is a red X and it lets you remove it. I suppose I had so much space junk, that the game had to render physics on each piece and ran out of memory. It may lock up in the next 30 seconds, but so far a couple hours and no game crashes. Let me know if it helps you. Hopefully we have solved one problem for the xbox, and hopefully will help the PS people also. Thanks to the people on this board that helped me figure out how to delete these items so I could test my theory.
