Random deaths issue.
So this has been happening on and off recently and I finally caught it on a log.
AFR's skyrocket lean, idle drops no matter what the IAC valve is, and it dies.
Ideas?

Your duty cycle at drops to 0.6ms at 260rpm and 32kpa. That's quite short.
At 1900rpm and 32kpa it's 4.1ms. That sounds more reasonable.
Are you falling off the edge of your fuel map?
