Not sure if it's the same for yours, but I had the exact same thing. Truck would run fine, then die while driving, with all gauges still reading. Let it sit for a moment, and it would crank back up. In my case, it ended up being the pickup in the distributor. Some how or another, once it got hot, it'd stop working. Ignition system stopped receiving a signal on when to produce spark, so it just.... didn't. Unfortunately, took a lot of parts swapping to figure that out, because I tested what I could, but some parts, I just had no way to verify without swapping out with a known good part. For checking fuel system, sounds hokey, but, pull the hood off, hook up a fuel pressure gauge that can lock on to the valve, and duct tape it to the windshield. See if the fuel pressure drops BEFORE the motor dies, or only as it dies. Mine of course stayed fine even as the engine died, ruling out the fuel system in my case. At least up to the pressure fitting. This was on an '87 with dual fuel tanks & V-8
