AKo, 13xBB, low flop

[betgo]

20-table SNG, 10 players left, 18 places pay, 9-player dinal table, I am slightly below average. Blinds 600/1200/75. Doubled up 2 orbits ago when open pushed from SB for 4th time with K4o and big stack in BB called me for the 1st time with Q3o.

I get AKo in 2nd position and raise to 3600 with T17K. 3rd position with T60K calls. The flop comes 552,r. I have 13.5K left and 9.5K is in the pot. What do I do?
