I did a search n either it's not addressed or I didn't use correct key words. If this has already been addressed, can someone direct me to it? 2 times now, driving 60mph and reducing to a stop, as I'm about 20mph all guages go to zero, all warning lights come on, engine continues to run normal, then approx 30 seconds later everything functions normal again. 2003 2500 4x4 6spd H.O. Thanks in advance

 

Sorry, don't have an exact fix for you. What does come to mind is past reports of some bad connections on the circuit board of some panels. Seem to remember something about on installation that tightening the attachment screws resulted in cracks in the circuit board. Removing the board and doing some solder work rectified the problem.
Do search on cracked circuit boards or similar words.
Let us know what you found and what fixed the problem.
