We found the seals on the right hand side drive motor was leaking oil into the brake discs.
By fitting a new set of hydraulic seals the problem was cured.

I have the same issue sometimes it drives then just stops , if we do get it to drive if we try and go up a ramp or put it under pressure the brakes seem to lock on ?
