I have a 2000 Dodge Grand Caravan that has the same problem. A friend of mine had the same van with the problem. He took his to the shop, they determined that there was a short in the wiring harness. It was rubbing up against something. It cost $200 to have it repaired. I'm guessing that is the problem with mine as well. If I hit a bump and the air is moist it will cause the gagues of the tachometer, odometer, and speedometer to drop. The ABS light comes on and all of the letters (R, N, D, etc..) for the gears are circled. It usually comes back on after a while but the longest amount of time was for 125 miles.
Check for loose wire or loose ground
Upper ball joints need replaced
