Cat in a box ~ truck in a quandary

On the deck there is a table with a small rug, an office chair, 4 other cushioned chairs, and a box I used while cleaning and drying walnuts fresh out of the husk. The box was from a store that cuts the side out for display, so I added a strip for my use – that’s why it looks odd.
They do use the table where they have a good view.
This week the choices were not the normal ones. Tzar curled in the chair and the shade. Rascal found the box and the sun to his liking. This is on the deck, newly added to the south side of the house.

The truck provided a mystery this week. The set-up is that I took it to the Ford dealer’s service shop for a 6,000 mile oil change and related maintenance. When finished, I went to the parking area and found it unlocked. That’s odd, something I have not seen before. Nevertheless, I got in and turned the key – – and nothing happened.
Then I realized the dash lights did not come on and there were no bells and dings as usual, such as for no seat belt and the door was still open. I pondered this, and after kicking the tires (just kidding) I went back and asked the folks what they did to the truck. Out two of us went. The service receptionist guy had the same results I did. Nothing.
This wasn’t like a bad battery, it was like no battery.
He went in and brought a power block that, when connected, should have brought all the lights and switches to life. Nothing. I stood at the front of the car watching the clouds while he went and returned with 3 others. While waiting, I heard something – an unrecognizable small sound that appeared to be from the car. One of the other techs got in the car, inserted the key, and the truck came to life and started easily. No problems.
Only the one person and I had seen the truck totally dead. The others joked that one had to know how to turn a key and went off chuckling to themselves. Except this isn’t funny.
This is a 2019 Ford 150, so there are hundreds of thousands on the highways.
Searching on the internet, I found several sites that had folks with similar “no battery” episodes that cure themselves. One Ford episode from 2009. There, a “chat room” response said to look for a main fusible link located by the starter relay. Here are two sites that describe the concept:

Understanding Fusible Links ~ The One Wire That Will Save Your Car!

These 6 Bad Fusible Link Symptoms To Watch For: Testing & Replacement [Explained]

I don’t find anything that says they can “cure” themselves – but that’s what it sounds like. I did find this statement “a power wire somewhere that’s intermittently shorting to ground” and there is something called a “self-resetting circuit breaker.”
Being well beyond my understanding of such things, my plan is to go back to the Ford service center and ask a few questions.

Weather:
The temperature this morning (Sunday) was 35°F. That seems to be the low for at least the next two weeks. Really, I don’t trust forecasts beyond about 3 days. That is a bit chilly, so I didn’t go out until about 11 o’clock.
I moved several hundred pounds of rock and dirt and changed chores in the afternoon. I settled for less active tasks.
