Solar Instict Surf sudden shut down after being exposed for 40 min to high intensity sunlight. Francisco Costa Rica

Hi Garmin Team,
I have a Solar Instict Surf that has worked perfectly until yesterday and this morning. I left my Solar Instict out in the sunlight for about 40 mins when I came back to pick it up it was quite warm and turned off. I left it cool down and turn it back on, no problem until this morning when I was running and in the middle of my run it shut down again. I got home plug it to the charger and let it fully charge. I haven't experienced the sudden shut down again yet but I am still curious.

I live in Costa Rica and sun intensity is quite high here.
