Remote PowerShell Session Ends quickly - Access Denied after a few mins

What would be causing me to be able to Remote Powershell to my Exchange On-Prem servers, run a few commands, then after about 2-3 minutes get the

"Connecting to remote server failed with the following error message : Access is denied."

I am running the following to connect, we have 2016 and 2010 in the environment...

  Start-Transcript -Path C:\Transcripts\EXCH_OP_$(get-date -format 'MMddyyyy').txt -NoClobber -Append
  $Credentials = Import-Clixml C:\Scripts\Credentials\ExchOnPrem_credential.xml
  $SessionOpt = New-PSSessionOption -SkipCACheck:$true -SkipCNCheck:$true -SkipRevocationCheck:$true
  $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $Credentials -SessionOption $SessionOpt
  Import-PSSession $Session -AllowClobber

Help please... Thank you

Try running your script under Powershell Admin.
or you can use the following in your script for credentials:
#Change Line 2 to 
   $Credentials = get-credential 

   #Change line 4 to 
   $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $Credentials -SessionOption $SessionOpt

Open in new window

Make sure to run under admin powershell
