I've had a simmilar issue with the D side UVCH, totaly random. What
I first noticed, When in would shut right down and not start, the Fuel pump would not cycle, you can hear it when it does. When I could hear the pump cycle prior to starting it would fire up and run great, till it shut right down again. No codes, 2 dealerships couldnt find the problem! The problem was the harness was chafing on the D-side valve cover, grounding out and shutting down or resetting the ECU. I shut the lights out in my Garage turned the key on to cycle fuel/Gplugs, pressed the harness to the valvecover and I could see and hear the spark. 1hr looking back on this forum, a 10mm wrench and a roll of black tape and the Gremlin was Dead!! Hooked on this site since! Also got the ford Diesel techs on here looking for Gremlins as well! Never did see my $320.00 back from Ford. Hope this helps!
