Welcome to the AndroidForums, soulpatroler.
Yes, I echo lunatic59's sentiments--its very difficult to track-down such an intermittant issue.
If you are overclocking (you didn't mention that you are), that's an obvious possibility (i.e., too high of a clock rate).
You could also try removing (temporarily, of course) any apps that you are suspicious of to see if the freeze issues go away. A logcat might also reveal what the last reported operation was at the time of the freeze (especially if you can find a repeat occurrence).
Anyway, good luck and glad you signed-up with us here at AF.
Cheers!
