My wife's van did these exact things this week. It was a bad cell in the battery, causing the voltage to drop making the instrument panel flake out and resetting the trip odometer. On Tuesday AM, it wouldn't start at all. Replaced the battery and all is well.

i found the problem! had some moisture in the plug going to tranny. must have been shorting out.
