Well that eliminates fuel, the SECM does require oil pressure to keep engine running.
Is this a Woodward fuel system?

Unit has auto shut down, and is getting signal from module in distributor to shutoff, I cut wire for shutdown unit will run and not die now but still have all dash lights lite up, believe it could be bad dash cluster but not certain

Can you bypass the lockoff to confirm no restriction in the valve. Maybe a plugged fuel filter. Sounds like a fuel delivery issue.

assure your fuel lockoff remains open when started.
