Sudden power offs are often indicative of heat issues, especially on
laptops. Does it power right back on and stay on for a long time? If not I
would suspect heat. If it does stay on, it may be a power management bug, a
bad power source or possibly a failing power supply in the machine.
If it won't power back on right away, or won't stay on till it sits for a
while, try cleaning the cpu fan - they collect a lot of dust.
