Shows a constant sync loss in that log, you'll have to look up reason 91.

Do you have a composite log of what's going on now that it is sort of running?

found out the problem. The cam sensor wasn't tightened down all the way, and a the cam sensor pigtail had a wire exposed. tightened the cam sensor down and ordered a new pigtail. Problem solved.
