There is a computer chip inside the distributor on my 1985 Nissan Pickup Trunk and I had the same problem until I replaced that chip twice. Some of the aftermarket chips are no good. Which Is a problem. I have the same problem with my truck right now. I can drive it somewhere and then park it and go inside a store. It runs fine until I park it and then try to start it back up again. Then it keeps stopping after I start it up. It takes a while to keep it running. I have to start it over and over again before I made it home. Only drove is about 3 miles.
