Recently had my ecu replaced the truck was fine for two days then it started dying on the freeway. I’d turn it off then turn it on again ; I noticed all the guages were good except the def guage it said empty, I turn the key off again and on and the def guage went to full . Then it would start and run for a couple hours then it would die. Its gotten worse. Now here at the house I turn the key and for a few seconds the guages are fine then nothing and then they flicker. Any ideas ?

Now when I turn the key on the dash lights flicker ???

My 2012 cxu612 is doing about the same as the above. I looked for the solinoid but couldnt find it ..
