Good Read, Unlucky Turn

Tonight I played a 45 Player $1.25 SNG.  I was playing well and was the chip leader when the following 2 hands came up:
I had appx 11000 in chips, blinds were 150/300.  I raised to 1050 from middle position with 66.  The BB moved all in for appx 5000.  My initial instinct was that I had him beat.  His bet told me he didn't want to see a flop, maybe AT to AK?  As I had him covered, I called.  He showed AK and hit a K on the turn to double through me.  Did I make a good call? You be the judge.  I would love to hear your thoughts on this hand.  On one hand, I made a correct read and trusted my judgement.  On the other hand, I placed 1/2 of my stack at risk on what was most likely a coin flip. 

A couple hands later, I had 88 in early position, I had Appx 4500 chips, and limped in.  The button limped, the SB and BB limped and checked, respectively.  The flop was K8T.  I flopped a set, I had appx 4200 left in chips and the pot was already 1200.  SB and BB both check, I check and the button bets the pot (appx 1200), SB and BB both fold, I reraise to 3000 and the button moved all in.  I call and the button shows K9.  I am in great shape to double up!!!  Well, the turn was a 9 and the river was another 9.  Running 9's unbelievable!!.  I bust out in 13th place.  I went from chip leader to busting out within 3 hands. 

I believe that I played the 66 vs AK correctly.  I didn't play it for my tournament life as I had my opponent covered by 2:1 and I would still have enough chips to maneuver with if I lost.  If I had won the hand, I would have been the overwhelming chip leader and would have easily been able to make it to heads up without even playing a hand.  Your thoughts?
