13inch.
It has happened many times. I tried to reinstall Mavericks, Yosemite, El Capitan and Sierra, but it still crashed. It happens randomly. When i watch videos on Youtube, play music on iTunes, or use Logic Pro X, it freezes and restart automatically in a few seconds. And I also ran AHT, but it passed.
What should I do? Really need help.
PS: I am not a native English speaker, so my English sucks.

As Toutou suggests, overheating has those symptoms. If your machine is running hot, take the back off and clean out the vents and other places where dust and debris may have settled.

Why not bring it to a service center and ask them to diagnose it? Could be anything, frankly.

But when it crashed, I put my hand on the air outlet. It was just warm.

I have been to Genius Bar, but they couldn't figure the problems out either.
Probably the hardware problems? But it passed many tests.

You can feel how hot it is on the metal above the left side of the keyboard. If that isn't hot when you have trouble, it isn't likely to be heat causing it.
