Can you describe the problem to a greater extent. How long has it been on when this happens? What are doing at the time? Do you have any really hot spots on the bottom?

Does it do this while on battery power or when the AC charger is pulled in or both?

by

I have come across several laptops which would randomly shut down due to heat. Dust built up on the CPU fan would retard thermal performance to a point where the system would power off to protect itself. These computers would do this completely at random, regardless of loading. A few short bursts of compressed air to the fans solved the issue. If you do use compressed air, never blow the air for more than a second or the fans my over spin which will often destroy them.

If your battery is dead, any interruption in the power supply will cause a shut down. The AC power in may be loose, try cleaning the socket and the input as these sometimes get crud on them.

on/off button ?

maybe the famous RSS (random shutdown syndrome) ?

does the mac this under heavy usage or is the failure not connectable to the usage ? (like: sometimes turns itself off after 2 minutes - the other day it switches off after 2 hours ?)
