So I currently have a 2014 fusion 2.0 ecoboost with about 47k miles on it. I was away for basic training the past 6 months and obviously havent driven it. I told my dad to go over and start it up every now and again and drive it. Long story short, the issue I am having is whenever I first got home and Started my car, it was having a rough time starting, and some sort of power save mode notification came up. As of now, it doesn't do that anymore, but the problem Im having now, once I start up my car and start driving, immediatly it will start stuttering and just die out as im driving the car. Everything is still lit up inside the too, Put some new fuel in ( there was about half a tank of fuel in it when I returned home on 12-16-2016 ) because I don't think my dad even put any in since he didnt drive it that much probably. Does anyone know what the issue could probably be? Like I said, its pretty much just been sitting in my driveway since iv been gone.
thanks guys.
Oh and I live in Pennsylvania where its currently cold.
