The pilot initiated the cross-country flight on a VFR flight plan in IMC conditions. He picked up an IFR clearance following his departure. After approximately 15 minutes of flight, the pilot said he lost power to the right engine due to induction system icing. This was followed by a loss of power to the left engine.
