2000 Accord when I turn it off when engine is hot& start again the engine shacks & engine light remains on?

The engine stalls when its hot and If I turn it off and star it again in few minutes, If I leave the engine untill its completely cold It would start without any problem. I have changed spark plugs and coil, the problem still the same. The mechanic advice me to change a MAP READER SENSOR for the cost of $200 CAD I dont know If I should do that or its just gonna be like flush the money into the toilet. Any Ideas..??
