Sounds electrical to just stop with no other symptoms.
Water temp sensor or connector, I have seen harness failure right behind the connector, internal, the insulation looked fine.
Oscillator and connector in front of the battery?
At this stage with the plugs fouling, you have tried a new set of NGK’s I’m sure.
Something to try with the fuel system, try clamping the fuel line off. I use a pair of those
small needle nose vise grips with fuel line on the jaws. Crank and see if it fires. If it does then open up the grips just a tad to be able to let through a little fuel. It may take a few tries to get it right. I perfected this procedure in dealing with the FC. If this works it can indicate an issue with the regulator and or damper. Sometimes it clears out injectors.
If you have been doing a lot of trying the exhaust can load up with fuel, disconnecting the exhaust from the manifold will bypass it for testing.
You might want to check wiring and signals for the air flow meter and control unit.
