Howdy, from Texas. I have a 2015 ecodiesel lone star 4x4 with 11,800mi. I just attempted to do a 2nd trip to the Pecos river near Pandale, Tx. I had a sinking feeling when my truck started an engine clatter, then rpms went to 3000...and was done.I noticed a post of a hpfp gear fail. I'm hopeful it may be the same. I will keep you posted once my truck is diagnosted.
