[watch physical console and/or serial one]

also:  double  check  any watch dog functions / hw / services  in  and
OUTSIDE the machine.

Also  check that no regular and huge change in power usage is occuring
on  the mains ... - if a classical light bulb flickers very noticable,
the  surge  may  be enough to get thru power supplies and  condis  and
trigger  a  reboot.  Suffered  a partial  second  brown-out  yesterday
rebooting  several computers - an old laserjet 4050 didn't even notice
:).
