Checked my fuel filters and they were clean as expected. The pre filter is a real nice 100 micron screen type. The post has a stone element. I don't like that type. I took it out. I have a real nice 40 micron Earl filter I put in it's place. I think it is a vent problem. I'll make sure the little can thingy in the trunk isn't clogged.

I had a problem with my fuel supply one day also, but not like yours. I have the FCC and I was in stop and go traffic. Mostly stop traffic. Truck was running fine and then quit, pushed it off the side of road after trying to start many times. Had no fuel pressure so I hot wired pump to battery and still nothing, than I noticed I had no pressure from mechanical pump. I disconnected the hose from pump to FCC and turned it over and finally got fuel coming from pump. Hooked it back up and has been fine since. The truck had a return line originally witch I used for my vent from FCC. I think the mechanical pump does not like not having the return line on it but with the return in place I don`t get a steady pressure.
I have not tried to solve this yet as I had other problems with a bad handheld controller, I just got it back and am going to put it back on truck tonight and try and start tuning.
Need to somehow get my cold idle higher as it does not run high enough when cold.
