I copied this from another thread(extremely gate sour) with a similar situation. Good advice in that thread as well.
I would work his butt next to the gate, then take him away from it and let him stand and catch his breath. Pretty soon he will figure out he isn't getting away with anything. I am a huge stickler for not riding horses out of the arena. I always get off somewhere, loosen the cinch and lead them out. But even better is to loosen the cinch and leave them tied to the fence in the arena before leading them out. It gives them an chance to relax and not associate the arena purely with work and the gate being done. Also If you have multiple gates in your arena I always go out a different gate than I go in. And I switch it up constantly.
I have even taken it a step further by working a horse outside the arena, take him in, loosen his cinch and tie him in there for a while until he relaxes, then lead him out.
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
