PowerShell Get-Cluster Remote API Error

I am running a powershell script to get cluster information.  The script works perfectly sometimes but sometimes fails on the get-cluster -domain command.  It will fail and then maybe a half hour later it will work.  Here is the exact error:

Message: Could not retrieve the list of clusters on the network.  A remote API error occurred.

ErrorCode: -2147022769

Any ideas on how to track down exactly what the problem is and correct it?
