What's causing the engine to die when it warms up!

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./

Troubleshooting an Engine that Stalls at Idle When Warm ...

I would check the coolant temperature sensor. This tells the ECM what the coolant temp is. The ECM uses this to adjust the fuel rate and engine timing when the engine is cold. If the sensor isn't letting the engine know that the engine is warming up properly, then the engine will continue to get too much fuel and the timing will not be optimal. This can cause poor fuel economy, engine flooding issues, and possibly backfiring.

Check the throttle position sensor. The fuel injector used for the choke is the only thing keeping the engine running. As soon as the engine warms up, the computer shuts off the injector causing the engine to starve.

EFI or CARB
we need this fact.
if carb , and you did a tune up.?
then the carb has issues (99% dirty caused) oldest story on earth.
sound to me, the carb is running leak, hot, just like all old dirty carbs do.

This is usually a problem caused by a bad water temperature sensor. There are usually 2 sensors with one working the temperature gauge and the second working engine controls.

The "cold start" sequence is similar to a choke in old cars. It needs the signal from the water sensor to trigger the cold start sequence. The cold start sequence enriches the fuel charge, adjusts timing, and increases idle speed until the engine gets a little warm.

Now if stalling when warm, you have other issues. Manifold runners are a problem on some engines.

Hey Dennis,, DON"T BECOME A PARTS REPLACER..(some people who "call themselves mechanic's" are just that!),.. .take this Dodge to a qualified professional... talk to them..
You say warm... do you mean full running temp?? .if so, you may be experiencing a vapor lock,, fuel "boils" when the engine is hot.. when it cools its no longer hot enough to cause this..(S.W.A.G.)
