This is resolved.  I wanted to include a couple apps from the app store in the image, but they were causing the sysprep issue. 
I'm able to pull a non-sysprep'd image with DIA.    When Sysprep is selected, AutoCapture Prep Tool gets minimized and doesn't progress on the sysprep task. ACPT version 5.6.0.2 Validation Checker passes normally.  Unattend XML was created with my same settings as my old Pre-1703 image that sysprep'd normally.     
DIA stuck in sysprep with new Win10 1709 image
