Typical of that vintage is a stop engine light for the ECM oil pressure sensor to fail. Mine did. It will intermittently report low oil pressure which will set off the stop light. The oil pressure to the dash gauge is a separate sender. Cummins has a fix. Changed the sensor to a low pressure switch, with a ecm update and a wire to an ECM pin. ~$500 total.
who knows? sounds reasonable to me but why only when hot pulling a incline at heavy throttle?
I thought mine was due to low fuel quantity, till it happened a week later with 3/4 tank. Could also be signaling lift pump going bad. They have seals that don't play nice with ULSD and end up leaking. ~$930.
Until you have the codes read we are all guessing. The cheap/easy fix is to replace the fuel filters and see if you still have the problem. The two filters are an FS1022 and a Racor S3201T on mine.
