Apple Developer Transition Kit Random Reboots

MY Dev Kit (arm) randomly reboots whilst I am
using it, surfing, email, Remote Desktop, ssh, ANYTHING..
  1. beta

Its very frustrating, when trying to use reply to an email
the machine just reboots (no error, nothing) and boots up
fast within 30 seconds ok back to desktop..

1-30 times a day.. no particular software being used.
does it any thing any time..

Suggestions
I also share this problem
Same here, sudden reboots, not kernel panic, mainly when scrolling. I also has black parts on my menu bar.
