Have you tried doing a PRAM zap?
Hold down Command-Option-P-R while turning on. Continue to hold until you hear the startup chime 3 times.
It also would wouldn't hurt to do a reset of the Power Management.
Hold down Shift-Option-Command, then press and hold the Power button for 5 seconds.

Good luck

This sounds like a serious issue that ought to be assessed by a tech. The machine shouldn't be randomly shutting down which makes me think that this may be a hardware fault. Pop into an Apple Store or into a business with an Apple Authorized Service Provider to get an assessment.
