1988 Dodge Dakota Intermittent engine running and stopping

Most usually this truck will start and run like there is nothing wrong with it. Once in a while, it will not start, although it always cranks well. The next day, when I try it again, it starts just like new, immediately, and runs smoothly. Its a V6 with EFI.

Once in a while, two days out of ten, it will start immediately, then I'll pull it out of the barn where it is always kept, to let it idle and warm up for 20 minutes (about every 2 or 3 days I do this regularly) and after a few minutes idling, it stops, just dies out of the blue, and will not start, even if I crank it repeatedly. Cranking speed is always good. Rarely it will restart. Usually it will not. After 10 or 15 minutes it will always restart!

It will also will do this occasionly (I rarely drive it) on the road, just dieing as I cruise down the road. Then it will not restart. Ten or 12 minutes later it will restart immediately when cranked, like nothing happened.

I am going to click the donate box and will put a 5 dollar check in the mail if you supply an address. But could you post it to the free question forum too? I'll make an effort to follow it there.
