I have a 1989 GMC s15 4x4 i had the same prob. it would run longer then 5 min. though maybe a halfhour. after pulling out my hair for a week and taking it to the dealer which told me " theres nothing wrong we can find " i discovered the ignition modual under the distributor cap was the problem. i recommend to replace with A/C delco part. i tried the cheap one and had to replace it again.
