Question type: Maintenance & Repair

I have a 1977 f150 runs fine for 10 to 15 min then
at a light or any long stops will die and will not
restart till the next day, thought it was the fuel
pump or fuel filter so changed both and is still
having same problem any ideas

Change the rubber gas lines coming from steel gas line from frame to fuel pump assembly hose is collapsing shutting off gas flow then returning to normal size after it sits for awhile. Reason I know this is because had a 79 f150 that was doing what yours is doing
