I was driving about 50 MPH when my traction control warning light came on. Shortly after that, all warning lights came on except the 4wd and Brake warning lights, and the rpm gauge stopped working. Then the 4wd and Brake warning lights came on, and rest of the gauges (i.E. Speedometer & temperature) stopped working except for the fuel gauge, and warning sounds began. At times, the brake and 4wd warning lights would go off very briefly, and the speedometer and temp gauges would start working again, until the brake and 4wd warning lights would come on again, and the speedometer and temp gauges would again stop working. The engine, power steering etc kept working, but when I stopped and killed the engine and attempted to restart, all the warning lights came back on with no engine turnover or sound. After a few minutes, the car started again, with just the engine warning light on. I began driving the car again and, after about 10 minutes of driving, the sequence noted above repeated itself.

Since this first instance, whenever I start the car, the engine warning light comes on. After driving for a few minutes, the sequence noted above repeats itself: the traction control warning light comes on, then the rest of the warning lights except for the 4wd and brake warning lights, then the 4wd and brake warning lights come on with actions as noted above.

I have replaced the battery, and have had the primary control module replaced, but the problem persists.

Sounds like the charging system isn't keeping up with the vehicle's electrical demands and the battery is making up the difference until it slowly runs down. Have the alternator tested for its maximum output current.
