Welcome to the forum
Reads like Fuel Pump is dying
When you turn the key on you can hear the fuel pump run for 2 seconds, it is not quiet, you will hear the HUMMMM in the cab, turn radio down, lol.
Fuel pump runs only for 2 seconds, but does this EACH TIME you turn on the key, so repeat on and off as much as you need to so you know what it sounds like, doesn't hurt anything, you can't "over pressurize" the system.
On the next No Start listen to see if fuel pump is running or not
Change the fuel filter, should be done every 5 years or so, could be clogged up but long shot at best, usually that would cause loss of power at higher speeds not No Start
