Nightmare Electrical

Try removing battery terminals, then reinstall them. (Engine off)

 

Check if you have a bad cab ground or power and maybe it's shutting #### off

 

As for disconnect/reconnect the battery, I'm not sure how much time in-between you gave it, but that procedure usually requires you give it at least 1 minute before reconnecting. (Enough time for electronics to reset themselves). It's one of those roadside "what can I do" actions when totally stumped, but actually sometimes works. lol

The few Internationals that I've driven had all been electrical nightmares, giving a dashboard electrical light show like the northern lights on many random occasions.
You might check this thread that deals with an 08 Prostar, and reference Heavyd's post. It sound somewhat similar to your problem.
Might at least get some hints from it, at minimum.

How about a little dynamite. Light and RRRUUUNNNN!!!!!!!

 

Sounds like the load shedding relay is stuck or failed in the open position. It will cause all these issues and happen during very cold cranks. Since the weather has been so cold in most areas the voltage gets drawn down so much it will hurt devices like this. A simple fix is the remove the center console, (plastic section right in front of the shifter with your cup holders on it). In behind that is the load shedding relay. The load shedding relay is suppose to cut off power to non-essential circuits when power is low. It is more of a nuance. All you need to do is bolt the two big power cables together, (doesn't matter which stud). Problems should be cured.

 

Any time, glad you got it!

 

That's what happened to me, thought I w as in a Sci-fi movie....got parked at truck stop for my 10 break and was summer, had my ac going, all of a sudden wipers turned on, lights flashed, etc all by themselves!! The driver next to me was teasing me said hey its not raining and what's the deAL with your disco lights, was embarrassing. Anyways our road service set me up to bring into dealer, tech found it quickly, yep load shedding relay, he opened it up, looked like a melted cheeseburger inside...they installed new load shedding relay, all problems corrected...what an experience that was. That was a 2012 prostar back then. For anyone reading this my load shedding relay was on the passengers side fire wall, easy to get at actually.
