Cluster Trouble Lights

[Sierra1500wt]

I have been searching forever, I have a 2013 GMC Sierra 1500 5.3 Litre (72,000KMs) the issues I am having is when I first start up the truck and go to pull away or back up but on a rare occasion all my Cluster Gauges lights come on then go right back off and temp guage and oil gauge drop to zero during this process and return to normal as well, it seems when I brake or goto signal, as mentioned it happens on a rare occasion. I don't lose power and do not have to restart the vehicle as it seems to stay running but it acts as tho its lost power or like you have just startd it (all lights coming on)

 

Its very very random but the pattern seems that when it does it, its when either I signal it may do it or when I brake it may do it, usually just moments after starting the vehicle from a rest period, then either you don't see it happen again until after its next start or not at all..

 

Very Lost on this one

Any Advise? Or Suggestions?

 

Thnx
