How might the stability of an ecosystem be affected if all of the decomposers were suddenly removed?

If all of the decomposers were suddenly removed, then nutrients would not be able to cycle back into the soil so that nutrient uptake by producers could be achieved, or at least not as fast or at as great a level, as it would probably soon enough become inorganic and unusable. Nutrients would be rapidly lost in the ecosystem and would not be able to be put back into the system.
