windows 10 powershell script problem

I generally run powershell.exe and keep a window open.  I can type in the command to run a script to shutdown the system at a specific time.  This script calls the following function.

Function Do_Suspend {
  Start-Sleep -Seconds 15
#  $msg = "Entering Standby at: " + (Get-date).DateTime
# Write-EventLog -LogName system -Source EventLog -EventID 1 -message $msg
  write-host "Entering Standby at:       " (Get-date).DateTime
  c:\windows\system32\rundll32.exe powrprof.dll SetSuspendState 0,1,0
  Start-Sleep -Seconds 10
#  $msg = "Waking up from standby at: "  + (Get-date).DateTime
# Write-EventLog -LogName system -Source EventLog -EventID 1 -message $msg
  write-host "Waking up from standby at: " (Get-date).DateTime
  Start-Sleep -Seconds 10  
}

The system then suspends.  When the system wakes up again it continues and returns to the point Do_Suspend was called and continues to process commands.  It is necessary for me to type in the command to do the shutdown.  When I upgraded to windows 10 I created a scheduled task to call the script to do the suspend.  But when the computer wakes up the script did not continue.  But when I did a ctrl-C the script continued.

I have two questions.  1. Why didn't the script continue after the wake up.  2.  Is there a way to interrupt the current powershell windows to run a script.

Thanks
