This is a turnament on party with about 200 ppl We are 10 away from the money and get AQo.

I dont know if this is just me being a calling station or if its a close spot and my play is ok -. It may just be a spew, but im quite tiltet after running into the nuts for an entire session and just want some feedback.

Info about villain:
I have him tagged as a good reg, seen him playing mtt's for up to 320$ buy inn, so prob better than me :p
Have only like 100 hands on him, but he seems fairly aktive and aggressive.

It a 8 man table, I have 27 BB to start the hand. And get delt AQo in the HJ.
Villain (UTG+1) opens to 2BB
It folds to me
I 3bet too 5BB
It folds around to him and he moves all inn and is covering me for the hole 27BB.
What should I do?

He is quite agressive, so I dont think he always must be nutted when he opens from EP and he might just be abusing me since we're close to the buble? I care more about winning this turnament than getting min cash and a 60BB stack would help me on the way so if he does this with 88-99 and maybe some worse suited Ax (that he bluffes with) it must be a call right. Or is he just nutted here too often?
It is a pretty big all inn and I kinda read that as weak..
How should one approch this spot? Should I just be a nit?
