I had a lifter that exploded and caused something like that. Valve stayed open then stayed shut. Beat the hell out of the cam.

another time had an injector bank start going out on the puter. Caused the same thing.

It sounds like the timing is jumping up and down. You might see something with the light on the dyno at cruise speed.

Can you drive it with the spout out, Timing locked and see if that is it. Go low to be safe.
