It could have been almost anything, but I don't see this as oil starvation. I see it as the ims bearing chunked, throwing a bunch of crap in the oil. When the bearing failed, cam timing went to hell and the junk in the oil clogged the variocam system resulting in misfires and difficulty starting.

Not much further you can do beyond running good oil (driven xp6 or 9), keeping the oil cool, and putting in a better ims bearing.
