Although I am against the TT for a number of reasons it should only be used on a horse that neck reins. If he doesn't, then direct reining with a shanked bit should be avoided since the dynamics of that bit will send mixed signals to your horse.
How are you asking him to stop? Have you used a one rein stop on him?
Aside from all that, and as mentioned before, you need to go back to the basics with him and that means a lot of ground work. He needs to learn, or relearn, basic commands and respect (as in who is in charge). When you ride him do a lot of half halts and serpentines. A horse that has been trained well will not forget that training after just a few months. I bought a 10 year old last year that hadn't been ridden in 3 years but it all came right back to her after just a little bit of time but I gave her clear commands that she understood and knew that I was in charge.
I've had him since he was a colt and my instructor did most of his early training, which was about a year of weekly lessons. I've been riding for about nine years.
I sink down a little and provide a solid 'wall' of pressure with the command "Halt", releasing of course when he obliges. No, I haven't.
