After checking the ground, battery terminals, the intake heater relays, intake heater, and all the relays in the power distribution box, I focused on the "Fuel Shutdown Solenoid" and "Fuel Shutdown Solenoid Relay". the relay was an easy check... but the solenoid was a bit of a p.i.t.a! I had to get a buddy to watch it while I cranked the engine... and it would not retract! if I depressed it manually it would hold in the "on" position but it would not retract itself!
On closer examination I could see separation with the epoxy seal and obvious corrosion/oxidation underneath.
Swapped out the solenoid and all is good!!!
