Question about 1995 Ford Econoline
When you start the van it will die after it has run for a couple min and wont start till it cools down takes about a hour I have replaced the cap/rotor/wires/plugs the problem is still there.
The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure

Offhand, a lot of possibilities that can cause no spark and/or deteriorating performance.
Hope this be of initial help/idea. Pls post back with error codes, how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Also remove carbon built up behind the EGR valve and the EGR passage tube.
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.

Testimonial: "I found the ERG valve bad. I sprayed carb cleaner. I didn't hear the engine rev but did notice a bad hose."
