Flush draw on paired board

[iceman5]

$1/$2 NL 6 max.

3 hands ago....villain limps in EP. MP limps. I raise to $14 with QQ in the BB.
Villain calls.

Of course the flop is Axx. I check. He pots it for $30. I call.
Turn is an 8. I check..he shoves his last $80 in and I fold. He shows A8.

So on to the hand....

I raise to $7 with [3h]. Cutoff, button (villain from last hand) and the BB all call.
Pot $28. Flop [Ks][Qh]. We all check to villain on button who bets $14.

OK, last hand he instapotted the flop with TP. This time he insta 1/2 pot bets the flop.

Anyone think I should fold this FD here? For some reason I get the feeling he could already have KQ and not be afraid of the flush which is why he bet only 1/2 pot this time. Thoughts? Obviously there are other hands he can have. I only have 1 hand for my read.
