UTG min raise, call, CU re-min? Now What?

I'm holding A,3 off in the BB. stack is still 1500 early in the tourney when the UTG min raises, one caller and the CU re-mins. should I call to see a flop or fold because I may be facing a big pocket pair? if I call, perhaps I hit a str8, two pair and double through...

questionable play I think when I folded...
