Hi!
Looking at your brief description can I guess that when warm the starter turns slowly? as if a flat battery?
If this is so then the starter windings and armature are possibly cooked??
Have you recently tried cranking the engine too much? or with a poorly charged battery?
When cranking the starter gets very warm and if not left to cool after 5 seconds of cranking can cook the wiring/armature internals of starter.
When your engine is cold the Windings/armature are too so will turn easier, but when warm all internals are expanded so more drain and heat! then causing the starter to revolve slowly taking a lot of power from engine and ignition circuitry.
This can also be caused from trying to start a vehicle with low battery, Volts go down Amps go up cooking/frying the winding/armature.
I am suggesting this as all I have to go on from the description STARTS COLD BUT ONCE IT IS WARM???? I hope this helps,
If it does please remember to press FixYa button as I have taken a lot of time to post the response.
Good Luck!

Won t stay running when first started. runs fine once its warmed up


This sounds like the temp sending unit for the ecm is bad. There are 2 temp sensors, 1 for the light/gauge and 1 for the ecm. The sensor sends a signal to the ecm to tell it engine temp, the ecm them adjusts fuel mixture for cold or warm engine.This works much the same way as the choke does on a carb for cold starts

First i would check the crank sensor by looking for rpm's on the tachometer or scan tool if you see any rpm's then crank sensor is good.Then check for leaking injectors and if they are not leaking then you will need to check the ECM it may have failed.

Starts cold when warm shuts off


May be the fuel pump, experienced similar problems in 1995 Intrepid. When the pump warmed up, it would start to loose pressure and car would sputter and die, but would start back up. If it started it would usually begin sputtering again and eventually die.
