    More information is needed about what exactly happens when it shuts down.

    Is the temperature nearing 100ºC? If temp get that high while running the battery that would explain it.

    Maybe, you've got a bad battery.

    Look in system profiler and see how many cycles and what the charge remaining is.

    Download coconut battery and iStat Pro to monitor your computer and battery.

    My first issue (of many) was similar. It turned out that the battery was defective, they switched it and the problem went away.

    The problem is your battery. It shorts out. Put in a new one and it's fixed.

    like ppl have said it sounds like its getting to hot. i wouldnt run it hotter than 70C. you said you computer is about 2 years old and if you have been running it around 80C for those two years it may be starting to fail. heat is the biggest enemy for electronics.

    This is sorta off topic, but are you serious that it can get to 100º Celsius? :eek: I'm thinking about purchasing a MacBook Pro, and if it gets that hot, I'm definitely gonna have some second thoughts. I cannot image a computer running at 212 degrees Fahrenheit. :eek:

    The MBPs tend to run hot, but definitely not 212ºF hot (I exaggerated a littler perhaps by saying 100). They can, as the operator noted get up around 80-90ºC.

    Running off of battery can produce more heat and raise the overall temp of the computer.

    @OP - 402 Cycles is quite a few cycles for the battery and it's full capacity is about a 1/6 of what a new battery would be.

    It may have been just the extra heat from the battery that triggered the shut off like you stated, but I'd bet you need a new battery.

    Don't worry, only the CPU gets that hot. You won't be boiling water (or your sweat) on the outside of the case. The case still does get hot enough to be uncomfortable sometimes if you are using it on your lap, but you can just put it on a book or get a "lap desk" if it bothers you.

    The Core 2 Duos in all recent MBPs are good up to 105C according to Intel. After 105, they will start to throttle down and at some point force the computer to shut down.

    That's a bad battery. You have over 400 cycles, and the full charge capacity is very low. You are lucky it lasted this long, though, since Apple only guarantees them to 300 cycles.
