Thank you very much for taking the time to veryify my results. All I can assume is one of the components is very unresponsive at a certain temperature. I hope its not something like bad ram. I don't know anything about the way these units work. I'm glad you could veryify what I found though, it is defnitly repeatable. I know acurasquirrel also verified this for me at like 3 in the morning last night. I appreciate so many people helping me out on this temp testing. I feel the answer to the problem is near at hand!

I work in the technical field. I have seen things done by operators where a certain batch of product (all made by the same guy) only has say, half of something soldered to the board. I have also seen chips not fully inserted and various other things. I hope it is something simple like only half of something soldered down to the board. If it isn't obvious, support will have to cool separate components to see which is failing...
