This sounds like the drive belt keeps coming off? Usually, this happens because grass/dirt gas built up on the drive pulley on the gearbox, and pops the belt off. Usual cause - damage to the plastic cover allowing grass and debris in, or a damaged belt (likely if it fell off and got chewed by the blades).
