1997 F53 ford 460ci fuel problem

On day 3 of a 5 day trip after driving about 325 highway miles once off the highway, motor started to sputter and die. No check engine light. Managed to get parked in campground for the night. About an hour and a half later motor started and idled fine. The next morning MH ran fine, headed to destination about 150 miles of highway driving. Pulled off at exit and again it wouldn’t idle, sputtered and stalled. About 1 hr. Later it started and we drove 5 miles to the campground. The first time it happened we had 3/4 tank of gas, second time a little more then 1/2 tank. Since arriving I have changed the fuel filter on the frame rail. Insulated the fuel lines from the frame rail to the back of the motor, changed the air filter. I am planning on replacing the fuel pressure regulator next. Any suggestions, or ideas? Lastly I am thinking about adding an inline fuel pump. Has anyone done that and if so what pump did you use and how did you wire it? Thanks for any and all help!

  • Try loosening the gas cap
    If the cap is bad, it won't allow air into the tank as fuel is used
    Causing a vacuum to build in the tank

    Might not be your problem, but it's a cheap easy test, and a cheap fix, IF it is the problem
  • If it happens in area where you can pull over, do so, turn off engine wait a couple minutes and try going again. Possible that you have a plugged catalytic converter.
  • So many things it could be.
    Does flooring it help? Could be the EGR valve sticking. You can disconnect and plug the vacuum line to it to see if it stops. If it does, replace it. Dont leave it disconnected.

    Also posible the IAC is acting up or the imfamous electronic ign. module is heat sensitive.

    Being fuel injected, I would not add another fuel pump. If the one in the tank isn't doing its job, replace it.

    I'm sure there are more. :(
