    iStat Pro will give you accurate readings of your temps and fan speeds, among other things. Use that to track your temps, so you know if the shutdowns are heat related. The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat (around 100C/212F - 105C/221F, depending on your processor). It won't damage it by shutting down. Heat-related shutdowns are performed to prevent damage.

    i started seeing this behavior almost triple in occurrence on my macpro after i upgraded it to lion. To fix it, i gave my computer a nice compressed air cleaning, especially the video card. No automatic shut off has happened since then.

    Maybe they beefed up the temperature sensor code in Lion to reboot more often when the machine starts to overheat.
