I got a 2004 5.4 and the damn thing stalls and idles rough when it gets warm. Was thinking fuel pump but now am thinking everything from vac lines to cleaning throttle body. Should i just do it all or anybody have any suggestions to start narrowing things down?

 

If it's running that bad, get the OBD codes read. Betcha there is a pending code.

 

You could spend a fortune shotgunning it. Get it diagnosed.

 

how does it act on hot restart?

I agree you need to spend some time or money and get it properly diagnosed. Nothing worse than spending money replacing perfectly good parts
