For it to start back up I’ll prime it and I’ll hold my foot on the pedal, but it won’t start up right away I’ll have to crank it for awhile. I do have a fass lift pump and no check engine light come on
Sounds like you need to be sure the lift pump is working and actually pumping fuel. When was the last time the filters were changed on the Fass?It will die when I come to a stop or slow down. It doesn’t throw any codes. Could this be a fuel pump issue?
