2020 Suburban - total lack of electricity - then it comes back

[Cottage hill bill]

Started the Suburban this morning, no issues. Drove about 20 minutes and parked. Walked around for 30 minutes and got in to leave. Absolutely no electricity. No dash lights, turn key, no click no noise, nothing. It was as if there was no battery installed. Called wrecker. Sat for 5 minutes, opened hood, lifted cover on positive battery terminal, closed everything, got back it truck and it started right up like normal. Drove home. Have started truck several times since, no issues.  Testing between positive terminal and ground on hood brace, voltmeter shows 14.45 volts while running. Any ideas?

I had a Suburban a little while back and was having issues left and right. Contacted California Lemon law Center to see if something could be done about it; they were able to get all my payments back and even some on top. Would highly recommend any of you who are experiencing issues with your cars to reach out and see if you have a case.

A friend of mine had a problem just like this with her Toyota.

The problem was a weak battery in her key fob.
