The truck is well cared for and fuel that cane out of the fuel filter was crystal clear. Fuel pump was replaced about a yr ago. My fuel pressure is stable at 30-32# at all rpm when stopped so I have kind of eliminated fuel as the issue. But still a possibility, just don’t want to drop the tank if I don’t have to.Wonder what inside of the tank looks like? A crudded up sock on the fuel intake can cause problems like this.
