Warning lights at idle?

My truck has started throwing warning lights if I idle for too long. The 4lo, VCS OFF, and parking brake light start blinking, and the traction control light and the abs light come on solid. I also lose most of my gauges except for the fuel and battery gauges. The gauges come back when I start driving again. The warning lights don't go away until I turn the truck off and on again. Nothing actually seems to be wrong with it, and it only happens when idling.

Any ideas? I haven't had much luck with google.

 

I’d start by checking all my grounds. That means the battery and all the body grounds you can find. Then check voltage at idle. Either your battery may be going or your alternator. At least that’s the easiest fruit to grab, and a good start

 

I'll check all my grounds. The battery is new and the alternator was good when I replaced the battery.
