I recommend using the proprietary Pi cable and a UBS/Surge protector when possible

But yeah, three failures is no good. Just out of curiosity, did you check if the SD card had failed?

100% use only the RPI AC cable.

Beyond that, SD card corruption was my biggest problem.

I repurposed my Pi 4 as a general purpose Ubuntu box and flashed the firmware to boot directly from SSD. Smooth sailing ever since.
