bring a broom stick with you and give the fuel tank a couple smacks the next time,if its the pump i should start right up.Every ford i,ve had did it as the pump dies.also keep the tank at least 1/2 full at all times.

And if that doesnt work...jam the broomstick.............in the radiator! yea..thats it! the radiator!.. 
Another thing you can do is take the ECM into Autozone or a parts store thats tests ECMs. Sometimes as they go out...they will work fine when they have cooled down for a few hours. When they start getting warm, they will croak until the are off for awhile.

Just did all my wiring in my 84XLT,and if the switch on top of the column wears enough where the rod from the key cylinder engages it and it won't crank the starter,you can adjust it (the switch behind the panel) by loosening the nuts and moving it ever so slightly toward the steering wheel.This gives the rod more throw!

Maybe.. maybe no, but.....
I was talking with the tech at the shop yesterday about the Bronco (she's going in for a fix on a 'high speed miss', but I digress) and we got talking about odd things that vehicles do...
He described a scenario similar to yours, 'engine quits when warm, won't start. Let it set and cool off (2+ hours?) and it'll start right up.'
(He marveled at how many fords came in on the back of a tow truck for that exact problem...)
... and the culprit 95% of the time for him??? The Coolant temp sensor. Allegedly when this thing goes out it starts indicating that the engine is running hot... to the computer.. which promptly starts putting more fuel to the mix... "dumping" was his term.
From his description though, this one often exhibits signs of a very rich mix.. black smoke, run rough as a cob, etc.
Odd one that, can't say I've run across that myself but sounds a bit like your woes..

if the coolant temp sensor was recording high temperatures, it could indicate a lean condition, which could in turn cause the massive fuel dump into the mixture, which could cause the O2 sensor to read a rich condition and lean out the fuel...etc, etc. all these problems are interconnected, i've learned. one thing goes wrong, and all the rest seem to show up as well.
my dad had an F150 that did the same thing. started, ran fine, then wouldn't do a damn thing when it got warm. turned out that there was a coolant sensor like i decribed above. it just got to the point where the ECM wouldn't let the engine start, for whatever reason.

Last year the I had similar issues ('93 XLT, 302) except for the stall. Engine started fine when cold, but after as little as 5 minutes of running and you turned it off, it would not start. Essentially, the engine then flooded itself out...temp sensor read COLD engine therefore cold start...give me more gas it said. To start it, you had to press pedal to the floor and go throught a basic flooded engine start. Mechanic put it on computer,read a bad temp sensor...fixed. However, my engine never stalled like you had happen.
