Thanks for your reply, David.
Problem SOLVED: it was the old HDMI cable from a HD Apple TV I was using. Replaced w/ a new HDMI Hi-Speed HDMI and it works great.
You seem already to have done all the diagnosis possible for this problem and your description suggests it has a fault. Take it to an Apple store with your sales receipt for inspection with a view to replace it.
It wouldn't hurt either to take a video of it restarting as in your description.
