Well my lucky streak just ran out I guess. 
Been reading about all the problems with the 6.7 but I was hoping I would be an exception. No such luck. 18050 miles and one year old..new fuel filter at 15k miles,.engine light comes on ...goes off...comes back on..truck starts to chug and sputter...
no smoke...no chimes...no overhead alerts, no overheating..nothing..just quit. She will still restart quickly but even a little feather on throttle and she chokes down..1-2 mph speed. Not bad fuel..went through eighth of tank...about 80 miles on trip meter since last fill up. Sounded like it wasnt getting fuel or maybe DPF was plugged up, EGR plugged up?
Too many short trips? Lift pump or injector pump?
I will bet it has something to do with the emissions control interventions)
She is sitting in Donovan Dodge Dealership (sierra vista AZ) driveway locked up for this Sunday night. (they had gates locked and tow unit could not deliver her into the lot area).. So will get up first light and get down there when they open and explain my problem. I will let you guys know what happened. Still under warranty but dealerships still scare me.
PS: Tow unit was flat bed. I asked why the flat bed? Tow unit driver said "you cant tow 2 tires up and 2 down with these trucks...either 4 down or 4 up is the only way cause it will mess up the tranny."
IS THIS TRUE? (still a newbie and learning)
Thanks for letting me vent and purge.
