My car is doing the same thing. I have a 2015 1.5 L ecoboost with 46k miles.. I can first get in my car in the morning and drive several miles, over 60 this time and drove like a dream. When I stop at a place and go inside like a store and then return and try to leave, it starts stuttering and stalling.. I have to go through about 6-8 stalls and restarts before I can get going again... I took it to the Ford dealer ship and of course it never stalled on them once.. It never threw a code or an alarm. I love this little car, but my love is slowly turning into anger, cause I have beautiful black paper weight setting outside my house.. Can someone that has had the same crap happen to them tell me what to fix.. I've had the whole fuel system flushed and cleaned. I've even tried higher octane gas but that doesn't help either... I was gonna replace the low fuel pressure sensor next, but I just read that HDrider09 has tried that with no luck.. I'm all ears if someone has a fix..
