Help me with the end game.

[riverruss]

Some background first.I have played about 2000 low buy in MTT's over the last 2 years showing a ITM of 1 in 5, with 1 win in 40 & FT 1 in 10.Roi 140%.
I think I have a reasonable grasp of the fundamentals of tournie play but feel I could do better.I seem to have an uncanny knack of donking off big stacks late on.
This hand that just happened is a perfect example.

Prima rebuy tournie,I had been in the top 10 since the add-on.
Just moved to this table 17 left 1st hand at table.
3000/6000 d(next level in 2 mins)
Hero BB 117,000 (3rd in chips)
Villain SB 208,000 (chip leader)
All fold to villain r 24,000,I push with ATs he shows QQ no help from board Im out 17th.
My thoughts were I am only interested in top 3,my M will be 6 in 2 mins,he could be stealing with a wide range & ATs is good enough.
This being my 1st hand at table with no knowlege of villain would you just pass this and wait for a better spot,just call & re-evalute on the flop or do you think my push ie +ev in this situation & I just got unlucky.
Any thoughts would be most appreciated.
