Well, it sounds like something in the area of a power or heat problem.
But, it is hard to tell.   dmesg.boot will not tell you much about
what caused the system to go down.   It only contains information
about it coming back up.

You might try and look in to /var/log/messages et al.
But, I would check on power consistency and if any component
is heating up.
