Most likely seat switch is out of adjustment, or, switch and/or wiring might be disconnected or damaged.Engine runs smooth on idle, but dies when speed control pedal is pressed.

Thats definitely an issue with the safety switches or wiring. I just ran into the same thing on a BX25. There are 2 on the seat and 2 PTO safety switches on mine.Engine runs smooth on idle, but dies when speed control pedal is pressed.
