Deploy VM using Remote PowerShell

We're trying to write a script to deploy VM's using Remote PowerShell.  If we execute locally it works every time.  If we execute remote it hangs in the same spot every time.  Anyone have any ideas?

$session = New-PSSession -ComputerName localhost -ConfigurationName Microsoft.PowerShell32

Invoke-Command -Session $session -ScriptBlock {
