Would you bust on this hand?

[Miscreant]

Preflop this is close between a raise and a fold at this point in the tourney out of position. Post flop its hard to put him on a hand you beat, he knows you have a big hand so he needs a monster hand or draw here to reraise, Ax is just calling, AK is raising preflop, A7 is folding preflop (unless they are bad and its suited and might just call after you raise the flop), most flush draws check or bet weaker. You can pretty much rule out AA or QQ, they either raise preflop or check on the flop. I think the only hands villian could have are KTc(15%), KJc(15%), 77(45%), AQ(20%), or A7s(5%) .. Going broke here isnt terrible but Im looking for a better spot with no reads.

Of course thats with 5 minutes to think about it, with 60 seconds it might hinge on other factors like his timing, if I have something else I can be doing, or if the payout structure is top heavy.
