Belts can be reliable. The ones that your escort engine uses last a
long time.
Maybe not as long as a lovejoy coupling, but still a long time.
But you probably can not use a lovejoy coupling as your engine is
unlikely to produce 50 hp at 1800 rpm. You may have to run the engine
at 2400 rpm to get 50 hp.

cruise control (use as governor) will fill that bill easily.

I don't trust belts much.
