Crowd-sourced diagnostics!

I recently sent out a help request for diagnosing a car that intermittently dies while driving. I’ve attached two files of the CAN data covering two occurrences of the car spontaneously shutting down. If anyone can find the key to why the car shuts down, I’ll buy you lunch!

Data2

Here are some charts of Data2: The first one is all of the data and the second one is zoomed in to just the area surrounding the BUS HEAVY error.

I simply sorted the message IDs and assigned them integer values. Here’s a key:

(They’re not exactly in order because the spreadsheet got a little bit confused by the hexidecimal numbers, thinking they were text.)
