AKs loser for me

Hi, I've played just over 67k hands and I'm making a good profit with a win rate of 7.6bb/100 hands. However, I have noticed that my AKs are losing overall and AK is only just making money. Some people say AQ and AJ can be problem hands, but I'm making a lot with those hands so I would like you to help me with my AKs.

Heere are a few hand histories of big losses:
Hand 1

Party Poker No-Limit Hold'em, $ BB (10 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

SB ($33.30)
BB ($96.53)
UTG ($8.13)

UTG+2 ($20.25)
MP1 ($67.05)
Hero ($49.50)
MP3 ($29.52)

Preflop: Hero is MP2 with Khttp://www.flopturnriver.com/phpBB2/...iles/heart.gif, Ahttp://www.flopturnriver.com/phpBB2/...iles/heart.gif. SB posts a blind of $0.25.
1 fold, UTG+1 calls $0.50, 1 fold, MP1 raises to $2, Hero calls $2, 5 folds, UTG+1 calls $1.50.

River: ($101.75) Thttp://www.flopturnriver.com/phpBB2/...es/diamond.gif (2 players, 1 all-in)

Final Pot: $101.75

Villain was 29/14 so I think the big mistake here was probably not re-raising pre-flop.

Hand 2

UTG bets $5.51, Hero raises to $11.02, UTG calls $2.44 (All-In).

Final Pot: $25.82

Villain 40/7, but that's only after 30 hands. I think I should have re-raised on the flop to make him throw those 7s away and show more strength.

Villain was 44/14. Not to sure if I could have gotten away from this one, what do you think?

Villain 31/4. Should I have just called or folded? Obviously the re-raise wan't too clever.

They are the four biggest losers so if you could have a look at them and give me your opinions I would be very grateful. I've added my little view at the bottom of each hand so you can correct me if necesary.

Thanks
