SharePoint Search Services Keep disabling on their own

Every now and then after patching I have seen SharePoint Search services in the service administration window automatically disable.

I am not sure why this happens but here is the fix: (run it on the search servers)

Get-SPEnterpriseSearchServiceInstance -Local | start-SPEnterpriseSearchServiceInstance

After you run that go into services and enable the services and start them, they should stay up now.
