1996 ford was warming up then died

Ranger not ford f100 Ranger.
When did it last run perfectly, last week, last decade or? never seen it run right..
lots of causes over up to 50.
I gets warm means engine,or outside air? temps.

so the spark plugs are bad or fouled. replace those old HV spark wires now.
it's over heating? the engine.
bad fuel
the classic answer is
bad engine, bad spark, bad fueling , in that order
or is the cause (or EFI failing)<< sensor etc.
this USA car (if is ) can OBD2 scanned easy, scan it.
do you want us to guess,? only.
or do tests, will you buy test tools to solve this?
there are tests for each cause of failure.
die out we call stalling engine,
when it wants to stall, can the fast right foot save the stall?
I guess car engine starts and runs cold? every time?
ever get a turn up,

engines 1996, diagnosis is best done, knowing first what is there,

2.3 L OHC I4, Pito LL23 4 cylinder but 8 spark plugs, yes.
3.0 L Vulcan V6
4.0 L Cologne V6

so when dead, and warm dead, check for dead spark?
check engine compression above 150psi on all cylinders
check fuel pressure when dead./

Sounds like a bad crankshaft position sensor to me. Those often go bad without setting any codes.

It is sometimes difficult to determine exactly what is wrong with the 7.3L engines. Many times it is hit and miss for the do-it-yourselfer. It sounds like you are getting enough fuel at first and then fuel is being constricted. You might want to try changing the fuel filter. Sometimes debris becomes lodged in the fuel tank switching valve which would require cleaning the valve or replacing it.

Replace the idle speed control and check the TPS voltage

they are vapor locking ive seen this on fords many times ,take the fuel caps off and clean out the little holes in them, or replace them or leave them a little lose!!!!

If it was a dealer, go back & have him scan it for fault codes. Usually cheaper to have it scanned and replace one faulty part, than replace 5 parts before you hit the right one. Autozone & PEP boys apparently will scan for free if you bought it private.

have you had the ignition coil tested!!! good place to start.

You make have a valve cover gasket leaking. After 2 years of sitting it could have dried out.

You should have vaccum so your intake gasket is leaking you have to change your upper intake gasket good luck it is a big job
