Airbus A320 Airspeed Indicator

Does anyone else have issues where this will suddenly read as 0 and the autopilot will nose dive because it thinks it needs to build speed. Then the indicator will go back to normal and the airplane will be over speeding. Any idea what this could be?

First place I'd look is icing. Make sure your probe heat is on?

Sounds like pitot tube icing. Press the button on the overhead panel marked “probe window heat “ before entering clouds if the outside air temperature is at or below 0 degrees Celsius.
