Playing the rush - AQs

$150 200 player live MTT. Start with T4,000. 5th round, blinds T200/400.
Hero moved to new table ~10 hands ago with ~T2,000. ~7 hands ago hero moved all in EP and stole blinds. Last two hands, hero moved all in PF with AKs (no callers, showed hand) and QQ (called by 55, hero doubles up). Hero now has ~T6,000. Still don't have any solid reads, but table has been playing a little loose. Hand after hero had QQ:
Villain = UTG+1, ~T10,000. Only seen him play one pot which he took down with some aggressive betting. Played with him briefly on another occasion, hero's read of villain is slightly loose-aggressive.
Hero = CO, ~T6,000.

Preflop:
UTG folds to villain, minraises to T800.
