Pacy, are you on original battery and alternator? What's your year/mileage?

The main f/box wire issue will be more apparent as you'll have functionality that just stops working so don't think it is that. Not sure on the EDC issue but would think you'd also get a related code if it was that.

If you're on original battery, I'd start there first since your alt. seems to be charging upon startup. You can take it out and go to places like Autozone that can test the CCA (cold cranking amps) on it. As batteries age they degrade and may show 12V while sitting but only offer up limited CCA (which takes a beating in the winter). If the battery is toast I'd replace it, register it and monitor charging performance as you have been. If it continually dips then look at a new alt.

My money is on alternator but lets rule out the battery first.
