@ Garland, Thanks for the input. No codes tripped with the no fire situation. I would expect the same if it was missing an input signal.

@ Scott, I have been leaning towards a ECM. Prior to it arriving at my shop they (previous shops) threw parts at it. Cap, Rotor, Wires, ECM, Fuel S/D valve, Pressure Regulator, You name it. Originally I found the dash was shutting it down on high torque converter temp (30sec after start). I made the dash happy and then we got into the intermittent fire issue. After finding multiple harness issues, mainly the wire almost cut in half for ECM pin 10, to the field coil on "power supply relay" I thought I had something. Cleaned up harness, found ground strap at right engine mount extremely loose, added a battery to chassis 4 AGW cable in addition to the battery to engine 2AWG. At this time it has been starting all day after cleaning ECM connector with a full can of "CRC Electronic Cleaner"......fingers crossed.
