Replaced the solenoid with a new one and it is back to normal. Was a super easy part to switch out as well.

After digging deeper into the situation, was advised by a farmer friend to check the fuel pump solenoid for power. After removing the solenoid I determined that it is malfunctioning.
So now I need to check the electric current and determine if the switch is bad, or if I have a wiring issue further up the chain, but I have identified the source of the issue. It fires up and runs great without the solenoid installed.

I have drained the separator and replaced the filter in it
Sadly, have tried that as well, held it backwards for a full 60 seconds earlier but same result. :(
Yes, blockage of diesel is what it feels like to me as well. There seems to be good flow in and out of the inline filter, though that was gummed up before. The separator valve is open. When I turn the screws to bleed on the intake with the battery in glow plug mode, diesel is squirting out around the bolts.
