I have run into this problem before. The exhaust manifold coolant vent hoses melt and cause coolant to leak. The engine will then overheat because it can not hold pressure causing it to start shaking. I would recommend having a technician come out and pressure test the cooling system and determine where fluid is leaking from the line and replace it as needed.
