ok MLG, can I get away from this one?

Sorry about the subject. Just busting some chops. But would like a little feedback on this play.

Stars $10 semi turbo, or whatever they call it. Blinds go up every 10 mins, so you have to take some risks and accumulate chips. Blinds are 75/150, I'm UTG +1 with A/Q and about 1600 in chips. I min raise to 300, thinking that should represent strength based on my position. I get one caller, blinds fold. Flop is Q/J/9 rainbow. I'm first to act. I figure I have to protect my hand and any bet all but commits me, so I push. He has K/10 for nut st8 and I'm done.

Thoughts? Should I have made smaller bet on flop? Bigger bet preflop? Any comments are appreciated.
