Bluetooth random shutoff

It's over 30 days old, It's out of warranty. I traded in my Mogul for a Treo 700wx, this Treo is treating me soo much better! So much more responsive, the lower-resolution screen doesn't bother me one bit, since I don't play games much on it. I still have that random bluetooth cut-off though. Cuts off when I had Windows Mobile 5 on it, and-- well so far it hasn't cut off on me yet. I'm running Windows Mobile 6 Professional right now. I wonder if it's a Windows Mobile thing..
