Won't start one day and fires up first crank next day

We have a non standard ignition system! This is not in the factory location or even Factory wiring!

What else may be hiding behind it? I will leave this to DEL!

Why Do Folks make this harder than that is needed?
No standard for sure but just the dist/ecu/eng/trans are not stock. Would love simpler, PM me if you want to go into detail.
