Well, it would be fascinating to know if in that period between when it goes offline, and comes back up, the console is actually outputting a panic message. Could you hook up a serial console, or turn on crashdumps, if they're not already on? Silent reboots are hard to debug, but panics followed by reboots are a lot easier.
