Won't run truck starts and runs untill worm then it goes dead rich and dies , wont start again untill its cold again

SOURCE: truck starts, dies. truck runs good some days,bad the next

I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

SOURCE: Starts fine when cold, after running dies on idle then wont start

Sounds like the fuel filter is dirty and needing to be changed. It's cheap and easy to swap out.

SOURCE: Works with charged battery. Then goes dead. 89 volvo 240

Alternator is failing. Cheaper to replace than to try to disassemble and rebuild.

SOURCE: cabriolet runs for seconds then dies

Fuel filter clogged, cheap place to start anyway

SOURCE: Runs 5 minutes then dies. Won't start until engine is cold.

Try the WD-40 spray in intake of throttle body with air intake hose off, to see if it will kick at all, even for a second or 2. We need to confirm whether your losing fuel or spark when it dies. Ignition & fuel, can cause similar symptoms in this case.
