maybe someone can lunge him with you riding him, if he is good on the ground and the problem is at the beginning of the ride under saddle you'll want to correct the issue while you're in the saddle. You may find that doing the ground work helps to establish more of a respect for you, but I have found that if my problems are occuring under saddle correcting them while I am in it is what works best. If he calms right down and isn't hot then your problem likely sin't too much energy but rather he's somewhat herd bound and doesn't want to listen to you at first because he wants to be with his herd, once they're out of sight he lets it go.
If he wants to turn around when you ride out, carry a whip and if he turns to go back, don't let him and give him a tap to remind him that you're in charge and he must go forward. Be gentle but firm. My mare did this on her first ride out and it was like asking her to cross a creek for the first time, don't let them turn back and ask for them to go forward as you as little force as necessary, but enough to get the point across that you are the leader.
Rule of thumb is work on training whatever your horse shows your first that he needs to work on that day and focus on that until you make progress.
Anyways let me know if lunging him does have any effect as i am interested to know.
