2 MacBook Pro 15" mid 2014 suddenly shuts down
Hi,
So, my MacBook Pro has had this issue for a good while. I just picked it up again after 4 months of collecting dust, to see if its possible to fix it.
We´ve tried changing the heatsink without results. Or at least positive results.
I can be surfing in safari or playing CIV V which is the hardest thing this machine has ever done - and it suddenly shuts down without warning. I tried stresstesting it today both CPU and RAM and nothing happened, until the stresstest was finished, then it shut down. And then i can start the MacBook again, and it shuts down after a minute, or it can take an hour.
I´m kinda lost here, all help or propositions will be appreciated.
It is a 2.5GHz with 16GB and 256GB SSD
Update (04/27/2018)
So, I sent it to Apple.
They switched out the motherboard(In February), and it hasn't crashed once since!
Yay!

I would start by digging a bit deeper diagnostically. Get a good thermal sensor monitor app like TG Pro as well as this free app CoconutBattery post screenshots of the main windows of the apps so we can see as well.

I tried downloading said software but the Mac kept shutting down as soon as I opened safari. Took some screen grabs from console. I’ll see if I’m able to upload them.

This is how it looks. Here the MacBook has been on for 5 seconds. After the screen goes black the fan starts working hard. 15 seconds later the light in the keyboard turns off.
