Check the wiring harness that runs just underneath the front of the transmission.
Where the harness connects my insulation was about 1/2" short and couple of the wires were nicked from years of road debre. When 2 of them shorted my OD would turn off.
Reinsulate the wires "I used a vacuum hose" and has been just fine since.
