Why is vagrant shutting down the machine at random times?

Question

Vagrant

Hey!
I put homestead on vagrant, I work for the second day, the thing is convenient, but there is one BUT. For some reason, at different intervals (sometimes after 40 minutes, sometimes after 2-3 hours), the machine suddenly turns off. I work with the site, make changes, check in the browser - bam, the site does not open. I'm looking for what's wrong, I write vagrant status and I see the Saved status. I have to write vagrant up again and this again lasts from 40 minutes to 3-4 hours. Then again, all of a sudden, the car goes into the saved status. As if someone writes vagrant suspend. Why is it so?
