Have you checked the stop light switch? I don't recall without a diagram but I think there are 2 switches on the pedal. The one with the green/green red wires should not be connected across and the one with green white/green yellow should be connected. This is without the brake pedal being pushed. You could try driving it, pull up on the brake pedal with your foot while trying the cruise. That will see if there's a bind oranother problem there.
