Ran fine all weekend driving back to work and again roght around 3hrs into the drive it died same thing changed fuel filters cracked for a while fired up drove fine all week just drove and let idle for 3 hrs same thing. No codes are popping up on my cts monitor change fuel filter light stays on and won't go off come right back on when I reset it. Could it be my cp4? Or maybe my fass loosing prime??
Deleted and tuned (bought truck that way) fass 150, cold air intake, fuel filter "delete"

I wouldn't think its the filter. If your filter is that bad you will develop a low rail pressure light then go into reduced power. Lean environments can create a meltdown. To protect the motor it reduces power. Just experienced this monday. Must have picked up bad fuel. If I had to poke a guess it probably is loosing prime.

Turns out its a pressure relief valve.. my tank had to much pressure in it and didn't have anywhere to go so it kept vapor locking my truck thats why my when I dropped my fuel filters it would fix it cause it was releasing pressure. Haven't figured out which one it is yet. But the trucks drive able with the fuel cap loose [emoji23][emoji23]
