 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.
