Wonder if it could be something to do with the low oil shutdown? Although you should get a light with that provided your battery is good.
At those temps probably should run straight SAE 30 if your not already. The viscosity chart in the manual only goes to 110°F. I would guess your pushing the upper limits of both the engine and the electronics at those temps.
