Welcome to the forum, thanks for the donation, I'd check all battery connections. I hope you find the problem before something burns up? When the problem occurs, pick one circuit that doesn't work and check fuses. Use a testlite and check the fuse circuit for voltage. Some circuits are hot all the time, some go hot when you turn on the key.
Not sure if you can read that? When I tried to enlarge, it didn't show all the fuses. It's the fuses for the havc control assembly. You have to test when the problem is ongoing. If your afraid something is going to burn up on you, you might take it to a shop.
