1995 Dodge Dakota engine will run for about 30 min. then di

i have a 99 doing almost the same thing. mine wont start at all now, scince this after noon anyways, i ve been reserching it and i think your symptoms fit better than mine. try testing your ignition coil, also what size engine do you have i might have some specks for you. be anyway you need an ometer to test the resistance inthe coil. take off the plug, should be 2 or 3 wires, if 2 test resitance between them on the coil plug, should be somware between 3-9 but im not sure without knowing the engine size. a week coil will give you a yellow spark, and also ive have been told that a coil going bad will work when its cold, but will not when its warmed up. thats sounds like why its stalling and you cant start it untill it cools down. let me know what kind off readings you get, also check the resitance of all the spark wires, just curious. same thing, on probe goes in one end and the other probe goes in the other end of the spark wire, do one at a time so you dont mix them up, hope we find something, sam
