New Post: Unwanted Reboots

Thanks for the reply. I'll try to offer some smaller versions of the relevant parts of the log. I should add, that the three things that are mainly going on here (run cmd file, run exe file, and run another cmd file)...I can do this all from a batch file and everything goes smoothly--no errors, no reboots. Also, reboots don't always happen, but happen quite a bit.

Here is one PC that rebooted, its' relevant PSADT log portion:

And then here is my Deploy-Application.ps1 script. I'm only posting the part I've changed from the default:
