This may sound stupid but have you checked the battery cables
They can cause the truck to do some really crazy stuff

Re: battery dying , volt meter jumping up and down all idiot lights flashing on and o
Start with the obvious things. A loose or corroded ground can cause all sorts of sporadic things to happen. There are a number of them on all cars and I don't know all the locations on escalades.
Have you checked the battery voltage itself with a voltmeter (& not the one in the dash)?
The other thing that comes to mind which is my best guess without seeing it would be the alternator. If the alternator is failed or failing most cars will generally run, but on the battery only. Once the battery drains down enough it won't have enough power to excite the coils and create spark, and other systems in the car begin turning on and off. Radios can turn on and off, warning lights, gauges go crazy, stalling, rpm drop, surging, etc. It's almost like the car is possessed. Also check the cables coming off the alternator. The alternator can be fine, but it the cables that charge the battery aren't a making good connection it's not going to be able to charge. Also note that alternators don't aways fail all at once so it's not uncommon to have things seem to work and then a day later have a problem. Same can be said of loose connections. Vibration, humidity, etc can all affect whether a connection can be made one day and not the next.
