AWS EC2 Opendatasource to the same server - OLE DB provider "SQLNCLI11" for linked server "(null)"

Trying to run a Opendatasource query to point to the same server as the source server in AWS EC2, I got this message intermittently (once out of about 20 times, the other 19 times do get results back). Any suggestion will be appreciated. Thanks. Error:

Cannot create an instance of OLE DB provider "SQLNCLI11" for linked server "(null)"

Query:

select top 10 *
from OPENDATASOURCE('SQLNCLI11','User ID=test;Password=test;Data Source=10.11.5.11').[test].dbo.test
