I was driving down the interstate with the cruise control on set at 75 and it just died It didn’t sputter or make any sound or give me any warning it just ran out of power I replaced the battery and had the alternator checked I replaced the fuel pump relay and the fuel pump I checked the inertia switch also I need some help

I still have the bed off and the pump is not pumping

Please explain NVM

I went through everything i could not being a mechanic for a living the truck initially died while driving down the interstate i since fixed the fuel pump relay pcm relay the fuel pump and fuel tank pressure switch along with the battery and i had the alternator checked out still nothing so i went back over the fuses under the dashboard after looking at the 30 amp fuse again i noticed a little black spot on the fuse leg so I replaced it and the truck fired right up I thought it was fixed I drove it for 2 days everything was good then I was leaving work and it just died again while slowing to a stop same thing as last time just crank no fire this time I noticed that the gauges are not working or the odometer I’m at the point of sending it to the dealership to get it fixed so any help would be appreciated I’ve seen on other forums that others have had the same problem
