In system preferences/energy, select 'prevent sleep when screen blanks'
What may be happening is that the machine is sleeping, causing the VM to hiccup. It shouldn't do that, but this might be a workaround.
I'll give it a try, thank you.
Another thing to try is to pass the power status to the Windows 10 guest.
This way when your host ends up sleeping you can have the Windows 10 guest go to sleep first.
(VMware menu -> Virtual Machines -> Settings -> Advanced -> check "Pass Power Status to VM" )
