Default Stalls then puffs smoke?

I have a question. I would say that on every 5th start my car stalls and then puffs smoke out of the part in the red circle below. Does anyone know what might be causing this to happen?

Is that the charcoal canister for catching gas vapors from the tank?

That's your air pump and I do not know why you would get smoke from it unless there is a restriction in it up the line somewhere. What color is the smoke?
