Preflop is good.
Flop is normally a call with 2 strong overs. But you list his UT open at 16%, which is a fairly tight range. I get your equity vs his entire preflop range at around 40% on the flop. I don't think that is enough to call against a large cbet and no clear good cards for you. A spade and turned pair are good for your hand, but they are not really good, meaning you can valuebet or valueraise on them. And an 8/T/K while giving you a straight draw is not enough to do anything against a second barrel.
So I think with ~30% pot odds on flop and ~40% equity and medium-poor playability I can't see a flop call beating a flop fold.
(He doesn't cbet 100%, but still a good first guideline to look at hand vs open range equity. Your equity vs his cbet range is very similar here.)
If you have KsQd you have few percent less equity on the flop. But you have 3 nut outs, which play great. So with that hand a float would be fine.
That said, AsQd is just barely too weak to call, and therefor a very good bluffraise candidate. Your medium strength outs like 8/T/K/spade play better aggressively than passively actually, making it quite the nice check raise hand. (If an 8 turn you can't check/call a second bet, but if you check raise flop you can keep bluffing with a turned gutshot).
Turn you have an easy call. You have between 40% and 50% equity against his 2barrel range. With 30% pot odds and one street to play to which you have nut outs it should easily be call > fold. I would rather bluff raise a hand that is too weak to call, like KsQd 
Raising is also better than folding though, so I don't mind it too much. I see one problem though, he can reraise, and then you have a spot where you fold 15-20% equity in a huge pot, which is a disaster.
