Please perform the following troubleshooting:
(i) Remove and reseat the RAM modules.
(ii) Remove the Battery and reinsert it after cleaning the metal contact.
If the issue persists even when the AC Adaptor is connected then try to get into the BIOS and check if the Computer restarts or shutdown automatically. Restart the Computer and press the F2 key as the VAIO logo appears to enter into the BIOS window. if the Computer shutdown even when in the BIOS then service will be required otherwise try reinstalling the Operating System.

Could be possibly hardware or software issue. Boot with a linux cd (try ubuntu) and see if it ever reboots while running that.
