It seemed to me that this was an issue of the PS3 overheating, so what I did... Yea I know it's a little odd but I took a 3 pound zip lock bag of frozen hamburger I was gonna throw out, wrapped a towel around it and set it on the playstation. Then just put it back in the freezer when I'm done. Haven't had it crash on me since, just seems you need to cool it down. I'd bet chicken or steaks would work well, or maybe you could just buy a cooling system for it!
