Query Timing Out

I have a rather complex query that is timing out more than 50% of the time in Quicksight. Is there a way that AWS can prevent the time out without changing the query? I'm adding rows through the use of 12 unions which I think is the reason for the timeout (very much needed).

Error description is shown below when I run it in Athena Query timeout This query ran against the "ewa_prd6_ohs" database, unless qualified by the query. Please post the error message on our forum or contact customer support with Query Id: 2a089f79-463f-4d37-8ca7-52ca09d43362
