If the engine is lurching stopped (like popping a clutch in 4th in a manual car) then you may have stuck transmission or drive belt
It might be a bad seat safety switch (thinking you are not in the seat when you release the brake)
Or they might be all working (tranny and seat switch) and your engine is only working at 20% capacity and it can no longer turn the tranny. Do both plugs look the same?
I'm leaning safety switch, though.
