New to the page and having issues starting my 454

I have a 2000 crew cab with the 454, I have had this issue intermittently since earlier this year. The truck wouldn't start, it will spin over but not start then eventually start to smell flooded, so I start checking spark and other common checks and found I had a weak spark so I have replaced plugs, wires, coil, ignition control module, and cap and rotor and it ran for a while then quit starting again so I was pointed towards the fuel pressure so I've replaced the fuel pump and filter. After all that its driven fine for a while now not doing anything again I'm leaning towards a worn out distributor but am looking for any ideas or possible answers to my issue. Thanks in advance
