00' 5.4L 4X4 dies after about 20 mins.
Truck runs fine for 20 mins, then just dies. Will not start back up, till after cooling down. It cranks over, but no fire. It shows no trouble codes. I have replaced fuel pump, relay for pump and fuel filter, but still having same issue. Has anyone experienced this issue? Thx

You need to check for fuel pressure at the rail port and for spark if the fuel pressure is there.
This tells you which way to go for trouble shooting.
No codes suggest a basic failure before any code can be detected within the system or possibly the crank sensor or outside power source such as the PCM relay.
Good luck..
