The truck stalls while driving like it is not getting fuel. It started last year and now happens in all types of weather and more frequently. While you are driving you feel the loss of power and even pumping the gas does nothing to save it from stalling. When you attempt to restart you get some run on but it won’t start. If you wait for 45 minutes to an hour it will restart and you can continue to drive. I have replaced the fuel pump relay, the crankshaft position sensor. Any help would be appreciated. Thanks.

Two things, first this does sound like a fuel issue so we need to measure fuel pressure when this is happening. I would hook the gauge up and then just tape to the windshield so that you can see what it does when this acts up. Next we need check for codes. If this is a fuel issue then you may not have any but we need to check.

Here are two guides that will help with this:
