Help i'm at my wits end my 94 ram 2wd 318 truck runs fine ,starts fine But it stalls when it gets warm but only once if I watch the temp gauge and shut it off for 3 minutes and restart it it start and runs fine and it will run the rest of the day starting and stopping untill it sits and gets totaly cold again .i now start it and let it run for 15 - 20 minutes before i leave for work shut it off let it sit and then start it up and it works fine. Any Ideas

 

Basically something isn't going right when it switches to closed loop. Does it stall at idle or while you're driving?

 

does it stall repeatedly, or only the one time
beware, guessing might cost you a bundle in unecessary parts, but here goes..

if its repeatedly, i'd guess an electrical problem like coil.
check for 12v at the coil, check for spark at the plugs.

if its only once, and then "resets" and acts right, then i don't have a guess.

if its an idle problem, i'd look into IAC or TPS, and see if i could keep it running with light pressure on the gas pedal.

 

it does it when you are moving or stopped that doesnt seem to matter and only once like I said if you shut it off before its totally warm and let it sit after a couple minutes you can start it and it will be fine ,Its like a dirty or slow contact once it closes it good to go till it opens again. It sure has me puzzled.

 

if its an electrical relay problem, you could try swapping the relays for ASD and/or fuel pump, etc with something like wipers, horn, etc.

during the 1-2-3 minutes where it won't start, you might could check for loss of spark or fuel pressure.

 

do these relays have a cold and warm mode it does this like clock work if I dont let it warm up and shut it off first and just drive it .It will shut off within a 1/2 mile every time but it is gettig worse it started that i could just coast put it in neutral and restart it now it takes 1 to 2 minutes but its also colder out side.

 

Nope, relays either work, or they don't. No difference by temp. (at least, not by design......)

 

I have the exact same problem. Did you ever get the problem repaired? If so, what was the issue and what was the fix?
