Hi, Brian my name is***** will be assisting you.
While it does sound like you have a pump issue with this one I would recommend doing an actual pump test to see what the flow is from the pump. In order to do this you would have to use a pump flow gauge. It could be that you have a partial blockage in the wheel motor that is actually causing your issue and not the pump at all. The wheel motor blockage would cause a backup of pressure in the pump which would also explain the hose blowing off and the slow response when first beginning to move.
