Red Hat Enterprise Linux 7.6 shuts down only a few minutes after being activated

Start the server through Red Hat Enterprise Linux 7.6 and minutes later it shuts down.
But when I start with Windows it has no problem.
And I checked the energy flow and everything is fine.
The problem started yesterday 04-Sep-2019
I clarify that the server is not overheated and has had no reason to shut down emergency.

I appreciate your help
