3.0 dies while driving

I have been dealing with electrical issues on my 2004 3.0 for the past two weeks. First, the PATS light would come on while driving and turn immediately off. Then the truck would shut off in drive with the battery light illuminated. Today, drove it 10 miles no problem, then it dies in drive. Put it in park, tried to restart and nothing. No click, no crank, no nothing. I think that several of the fuses are acting up. I have replaced PCM relay, fuel pump relay and starter relay. Sometimes if I wiggle the relays it’ll start again. I removed the engine compartment fuse box and inspected the wires underneath, I don’t see any obvious issues. I cleaned the fuse box contacts with contact cleaner. It is a very reliable truck normally, no mechanical issues at all. Tested battery and alternator, they are good. I don’t know what to do. I also had the ECU tested and it passed with flying colors. Please let me know if I’m missing something here.
Thanks, Alex
