But run [F250] until it get thoroughly warmed up, shut it off, and it

aaaa clickety-click. Let it sit for 10 to 20 minutes (depending
on the outdoor temp) and it fires right up again. PITA at gas
stations.

Please list some of the things you tried, or replaced.

Ha. Starter motor, fender-mounted solenoid/relay, battery and (for
other reasons) the alternator & belt.

Haven't replaced the cables, all of which appear clean and well
connected but not (See Mike Terrell's post) oversized. Haven't
replace the in-tank electric fuel pump or other fuel components or
sensors.

Folks in another venue have suggested overheating of the starter motor
itself by the nearby exhaust manifold. I haven't figured out how to
cobble up a heat shield yet. (Getting a little old, stiff and creaky
for crawling around under a truck, don'tcha know?)

Other posts saved for thinking about, thank y'all.
Second sun had that prob. with a '68 valiant after he put a V8 in it,
exhaust leak would overheat the starter and it had to cool more than
an hour before it would start. he stopped for supper one night and it
wouldn't start when it was time to resume his journey. By the time I
got there to rescue him (90 minutes latter) it fired right up and he
followed me home.
