Also check the hardware monitor section of the BIOS, if possible, they
will give you an accurate measure. You can also check the output of "acpi
-V" to find out additional data for trip points (is available).
Is it a laptop or a desktop computer?

By your explanation, yep, looks like the micro is reaching a high
temperature and it shutdowns to avoid damage. Keep the system running
with the BIOS screen opened and watch fans speed rotation and system
temps... and keep it so for a while to see if it also powers-off.
