I lose alot in this situation :

UTG is 17/15/13 - has folded a couple of times to my 3-bets.

I just don't know what to do here ?

Definitely raise flop. If we're ahead, there are lots of cards we don't want to see on future streets. If he 3-bets, he probably has either overcards + flush draw, overpair (and likely better than yours), or a set, so we can safely fold. If he has overcards (not hearts) he's more likely to throw them away.
