Macbook pro randomly shuts off
My MacBook Pro (Retina, 15-inch, Mid 2014) is shutting off randomly. It specs are:
Processor 2.5GHz
Memory 16GB
Storage 512GB
Graphics NVIDIA GeForce GT 750M
Its former macOS was El Capitan and was updated to Mojave (full format installation), a month after the update it started with the problem.
A collage of mine with a MacBook Pro (Retina, 15-inch, Late 2013) 2.3GHz, 16GB RAM, 512GB, NVIDIA GeForce GT 750M; is having the same issue.
I installed again El Capitan and the problem is still happening, I took my computer to a authorized repair center in my country (Colombia) and they have no clue of what is going on, seems to be that they asked to apple what could be the problem and the suggestion is to try to replace both the SSD and the mother board but they I don't have any units to "try" those solutions so I must pay for the parts without knowing if it's the right solution.
Finally, what I did was to create a Ubuntu bootable usb 18.04 and have been using the computer for the last 44 hours playing videos on youtube and hasn't fail.
Any suggestion is pretty much appreciated
