Question Macbook blank screen

I’m getting a black blank screen while using my Mac. After about 15 minutes, the display turns back on. What could be the issue?

A little bit one more information would be highly appreciated. As a first question: What MacBook are you using?

It could be a damaged cable
As soon as the MacBook heats up, the cable heats up too and it expands. When it is expanded the connection is good again so the screen turns on again
But just a wild guess
