That is not a reboot. That is a crash/power off or something else. You might move your wake up the machine to say 7:40 and see if the machine still does it at 8am or then does it at 7:50 (10 min after reboot). If it does it 10 minutes after reboot that is often the default for the watchdog reset timer that will force power the machine (in bios) if the OS does not touch the watchdog every so often. If the machine has the watchdog enabled, there is a decent chance it is not getting correctly restarted after hibernation.
