When should I have folded this?

No read on these people. I had an extremely tight table image, not playing the last 20 hands or so.

I feel like this is a preflop fold. The guy has to know I have a good hand, so I feel like he would only reraise me with a monster (AA, KK, or maybe QQ).

Should I have led out like that on the flop?

PokerStars No-Limit Hold'em, $0.25 BB (9 handed) converter

Hero ($31.55)
UTG+1 ($28.40)
MP1 ($5.05)
MP2 ($52)
MP3 ($14.40)
CO ($16)
Button ($30)
SB ($10.85)
BB ($11.20)

Preflop: Hero is UTG with A, K.
Hero raises to $1.25, UTG+1 raises to $2.5, 1 fold, MP2 calls $2.50, 5 folds, Hero calls $1.25.

Flop: ($7.85) A, 7, Q (3 players)
Hero bets $4, UTG+1 raises to $8, MP2 calls $8, Hero folds.

Turn: ($27.85) 9 (2 players)
UTG+1 bets $17.9 (All-In), MP2 folds.

Final Pot: $45.75
Main Pot: $27.85, won by UTG+1.
Pot 2: $17.90, returned to UTG+1.

MP2 makes me laugh.

What's UTG's standard to make the raise preflop?

Any sense of that at all?

If it's not centered around AA and KK, AQ and AK are also a potential.

Making your flop fold g00t.

I am, however, afraid that we're both giving too much credit to him. But you gotta respect his aggression without a read.

I don't have a read on him but like I said I have an extremely tight table image.
