Got myself in trouble...then made a bad call....what do you think?

[Ben5505]

Stack sizes...

Hero--4200
UT--9000 about
MP+2--2700
MP+3--3100

Im in the small blind--blinds are 50/100

UTG min-raises to 200 which he had been doing very frequently so the min raise meant nothing to me. MP+2 +3 both call and I am in the SB with 10 10. I raise to 800. First question is what that too little? UTG calls and MP+2 calls. Flop comes K 7 3 rainbow. I lead out 900 UTG folds and MP+2 pushs for 1190 more. This was the second time I was in this situation with Villian. Previously he limped in MP and pushed when I raised from the button with KQ so I felt like he knew he could get me off of a hand. Anyways I made a crying call and he turned over AK and put my stack down to 1200 and change.

Thinking about the hand I feel I shouldnt have led the flop? Or I should have just pushed? Thanks for the insight.
