Finding/changing timelimit in LoadUI-NG load tests

I'm trying to run load tests and after about 7 minutes of running, I see the traffic decrease by 30 trans/s. 

We ran into a similar problem with LoadUI (Pro) v.2.5.1 where a test scenario was set to end after 15 minutes which over-rode the test wide limit (which was greater).

I'm trying to go thru the ReadyAPI/LoadUI-NG UI to find where that would be set for this newer version.
