Having a problem with engine idle.

Boat starts fine and will run fine for first 1/2 hour then idle gets a little rough and when engine is shut down restart requires full throttle neutral then will run fine again for 20 min or so and occasionaly stall but will also run rough.

Have had it into dealer but they have not been able to duplicate problem in the shop.

Any thoughts or ideas are appreciated
