If I had to guess your truck is experienced a 12V battery SOC (state of charge) issue where it's operating at the borderline threshold for what the BMS (battery management system) considers necessary for all the features.

A nicely equipped Gen14 truck can tax a 12V battery, especially if the truck gets driven lightly.

Replace the OEM battery with a higher quality/higher capacity AGM (Duralast, Interstate). Here's the one I used. It has been flawless, even with the truck sitting for weeks.
