Two things I would try. First is, go back to ground work and lunge him over the jumps instead of riding him until her can go towards the jump without scurrying forward at the last second. Second, I would do some approach and retreat with the jump, so walk him up to it, then back him away, and repeat this until he stops showing any real interest in the jump as an object. Then try it at the trot. Do it until he can approach the jump without expecting to go over. Then approach the jump and ask him to go over. I've never had this create a dirty stopper.
Peace, Love, and Ponies of all shapes and sizes.
