Out of the blue the other day the alarm just started going off, the only way i could stop it, was to pull the horn, fuse it crank and drive just don't have a horn now.

If the engine continues running for longer than two seconds, it's no longer in theft mode. You should be able to reinstall the horn fuse. One thing you might consider is low battery voltage. The alarm activated multiple times on my '93 Dynasty even though the battery was still strong enough to start the engine. New battery solved the problem.
