Power Saver Mode

[JD House]

Greetings all, new to site. Hope I'm not the only one with this issue...
On cold mornings my '19 2500 will go into power saver mode after about 5 min of driving. This mode will shed all power to the entertainment system.
I have to pull over, shut down truck, and on startup I'm back in business.
Dealer has no idea. Voltage and batteries are good.
Point of clarification, when I say cold mornings, I live in Southern California... So a cold morning is 40-50 degrees. If the outside temp is above 55 degrees I've never had the issue... Also it's not every day either. Hit and miss...
Any suggestions...
Thanks in advance.

Batteries are low, at least that’s the main culprit.

How long does your truck sit between drives?

Do you ever use a battery tender?

Ok, thanks
Seems to be independent of batteries, it has occurred after new batteries have been installed.
The truck is my main drive, but I'm a fireman and it does sit for several days when I'm at work.
Do you recommend a battery tender?

I would put a full charge to it, with something like a NOCO Genius 5, and see if it still happens. If it does it could be the IBS on the drivers battery.

Great
Thanks for the advice.

So now my truck and my wife have irritable bowel syndrome...great

Does it matter what battery I put the NOCO 5 on?

No, but if you put it on the drivers side made sure the negative is on the vehicle side of the IBS, not the battery side.
