usually battery, alternator, ecm , battery temp sensor, or bad connection any where in between. I had the same problem intermittently but the alt gauge would also drop to zero. Put in a new battery worked for a while then happened again had alternator tested at advance auto and tested fine checked all connections and they were good. I noticed the black plastic housing going to the field connectors on the alternator looked a little warped by heat . Replaced the alternator and has worked great ever since. seems like the intermittent problem is why the alternator test was ok.

When the check gauges light comes on it is telling you to check the gauges because at least one of the gauges is out of normal range. It could be low oil pressure, engine over heating or low voltage.
