Anyone experience their truck stalling out while driving, almost feels like running out of fuel and then restarts on its own? All of the dash gauges read normal, both fuel tanks full and the truck stops running and will then restart a few seconds later. The problem has occurred on both fuel tanks. I am thinking fuel pump or something similar. It's happened a few times and seems to be occurring more frequently and for longer durations. Any suggestions where to start

need to scan and perhaps see any codes. would be interesting to know if its losing spark or fuel when it stalls.

Check simple stuff first .. when's the last time the fuel filter has been replaced ?

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
