A pacing Paso is relatively rare.
I'd be looking for something physical that has changed. Is the rear hoof angle too low? Is the saddle pinching his withers? Is the weight he is carrying different? Does he have a pain issue? Have you changed the bit or curb chain in anyway? How long since he had a Equine Dentist do his teeth? Is his sheath clean?
If he was a fino horse, was it natural or forced? If forced, and your not forcing it any longer, you may have to make some changes, to get him to change his way of going, ie, hoof angle, weight being cared, type of saddle, etc.
Are you pushing him beyond his current physical conditioning? If they get tired (and many of them will never show it), the pace may be the easier gait.
