stalling

Hi , my 92' Maxima 3.0 vg30e sohc is stalling during the first ten to 15 minutes of running on cold start ups. seems like someone turns the key off, more of a cutting out. Seems to be on deceleration or at a stop light. Then some times on accerleration the car seems to cut out like you got nothing at the gas pedal then it comes back to life and goes. Also has any body had a problem with aftermarket mass air meters.
