I'm going to guess (note the key word "guess"!) that you have a loose connection to or in a control computer that's sometimes jiggling around and making the computer reset itself. I don't envy you in the least trying to track down that sort of a problem.
My thoughts also. Go under the hood and with the engine off unplug one at a time anything that looks like it goes into a control box. Look closely at the connectors and using a spray specifically for electronics spray each connector. That's what I would do. You say that you have had the battery disconnected, that will reset the computer also. I would also unplug the main fuse and check other fuses directly related to the computer. Double check those battery cables and ensure your ground cable to the battery and the frame is clean and tight.
I had a diesel generator once that stumped the best and it was a bad ground to the frame.
Have you used a code reader yet, my 08 Wrangler had a clock spring fail, it's the round device that controls airbag and all controls on your steering wheel, and I was getting flashing codes and
tones until I replaced it. It had an effect on my ignition switch as well.
