Why does my MacBook Pro Retina 2015 freeze?

Question

macbook

It hangs tightly, when the lid is closed, the screen does not go out. If you press the trackpad, then at first it clicks, but then it stops responding (as if the computer is turned off, there is no tactile response.) At the beginning I thought that the problem was the lack of RAM, but I have swap enabled. And even more so, this is happening for the second time when I watch YouTube, and when a lot of software was running at the same time, there was nothing like that.
UPD.

First of all, such a machine cannot freeze a priori (only in the most extreme cases of 12K installation) most likely in my opinion
1) Overheating
2) Virus (there are few of them, but the stick shoots once a year)
3) An unknown process that can lower the frequencies of everything and all at such a minimum that throttling starts and it just dies
4) The marriage of the device (perc, video, RAM, mother) anything, it is also possible
5) Try to trace when and how often this happens and what it can be connected with, I remember it was a problem with the video card, it hung tightly in a minute and it turned out that it freezes only if you don’t move the mouse (as a result, there was a trojan)
