Hi, @Rick Someone
Thank you for posting in Microsoft Q&A forum.
I don't use SCCM...and most of my questions just involve MDT Build and Deployments.
Then we can ask the questions with mem-mdt tag.
It could be better if you wait a minute or two after the OS boots before you resume the TS.
Also try rebooting the VM, there's nothing wrong with rebooting while the TS is suspended. It'll just boot back to the desktop.
