Re: I had a breakdown today...
Since you are not even getting a "put-put" out of the engine indicating that the piston is still moving in the cylinder, I suspect that something has come apart inside the transmission. The low idle may have been caused by a loosened/ relocated part dragging on something else inside the transmission/ housing.
Take the cover off and have a look.
