Both logs were cold starts. About 5 hours in between starts. E30 v1.5 still having -20 to -30 percent then car dies without external input.

Start up was rough, idled for a short period of time and again shut off. No code. High negative fuel trims. Immediately uploaded MHD OTS stage 2+ e30 map and it’s sitting here idling just fine. No codes and normal fuel trims
