Unable to Delete the Search Service Application from SP 2010

Cause: You try to delete search app through Central Admin and PowerShell but it hangs and will not delete the search application. 

If you run a Get-SPServiceApplication the ID is still listed.
 
Solution: Run: stsadm -o deleteconfigurationobject -id “GUID of search app from get-spserviceapplication” 

This will delete the search app and allow you to create a new one.
