2018 F3L stalling while driving - any ideas on why?

[DriftersWay]

I just repaired a problem very similar. Turned out to be loose battery terminals.
Battery was new but bad out of the box.

GWHIZZ -- I was kinda hoping maybe overheating due to low coolant but the ungraceful nature of your shutdown and the codes you described really point to a CANBUS problem. Since the left-hand switch module is a critical node I suggest you follow gkamer's path and look at these posts

I am told - several times now, and by several dealers - that the TSB for this does not apply to my VIN. So far, BRP is wanting dealer to restore to factory settings, remove my chargers from battery tender and on handlebars (GPS), and replace my Lithium Ion battery with BRP Spyder battery. Since I have not personally changed any factory settings, no issues there. Perhaps the battery is contributing somehow to the intermittent problem as it is now 5 years old (but still tests ok on load). Let's see how this plays out. I just want it fixed right.

Well, after much research and calling BRP 3X, I do believe that the "lithium ion" battery may be somehow contributing to my stalling issues - not be the best kind of battery to put in a Spyder. I bought bike like this from pvt. owner and discovered this the first time I pulled the frunk bucket out of curiosity. I personally would have put in a better battery, like Yuasa, from the start. Anyways, wish me the best. I do believe putting in a new Yuasa will fix my ills.

Did the new battery fix it?
