Suspect the ignition/power switch behind the steering lock they wear out and at times melt inside where the contacts attach, contacts even fall out within the unit and short on other inside terminals.

I have a 93 and they don't go out completely but when I first crank the truck, any lights that are on will all flicker for a little bit until it warms up. after its warm it doesn't do it.

Check battery cable connections at both batteries and engine. Even possible bad ground for starter.

X2 on the connections. Have seen issues just like this be caused by some corrosion on a battery terminal.

At least you have your priorities straight. Get all the hunting in while you are able. Hopefully that means until you are at least 90 years old or so. Not everybody is so lucky. I passed on a lot of hunts that I really regret passing on now.
