There are 2 cheap parts that will cover the entire spectrum. The crank sensor mounted by the bellhousing, and the ignition pickup plate inside the distributor. Most likely the crank sensor failing. I bought a truck non-running for $300, replaced the $40 crank sensor and sold it for $1500; Took me a bit to find it because I had to learn the system, but the system is REALLY simple.

Crank signal tells it when to fire the ignition and injectors. Cam sensor (distributor pickup) tells it when its at #1.

Now, the MS2 thaws a curve in this. I run a MS2 in my Charger on a 496. I have a similar tiny skip, but its enough to reset the logs as if it was shut off. Looking at the loggers, it looks like a crank signal loss, which makes it think the engine was shut off.

I would try a new crank sensor first.
