Mac Pro (Mid 2010) Randomly powering off

Hello!

I have been recently having an issue where my mac is randomly powering off. Monitoring CPU temp, it was high when it did it once (around 80 celcius) then later it did it while the CPU was on'y around 40-50 c. Checked the console after the last one and found this:

9/26/16 11:14:35.000 AM kernel[0]: process Adobe Premiere P[605] thread 15552 caught burning CPU!; EXC_RESOURCE supressed due to audio playback

This is the last thing on the log before it shut down. per how its acted all the other times, I unplugged it and plugged it back in as it would power down during boot typically unless I did that.
