P016F is a fuel system pressure control - low fuel pressure at high side fuel delivery related to power loss symptom.
As it happens intermittently - first thing is need to check any fuel leaks and fuel filter for restriction, if you are pretty sure that fuel filter is Ok then common faults is a fuel rail pressure limiter valve, suction control valve and faulty injector. If after fuel filter replacement problem is back then start with replacement of limiter valve, if no - then SCV valve and if same condition present then diagnose faulty injector that cause to pressure drop
