I just encountered a similar problem. Flashing new code would fail. When I ran idf.py monitor, it would continually reboot in a pretty tight loop. My solution was to erase the flash using: 

idf.py erase_flash -p com21

is your USB cable a charger cable only? This happens a lot. Charger cables look almost the same as charge/data cables. Though the heads look the same, sometimes a charger cable is slightly thinner b/c it only has two conductors in the jacket. Charger/Data cables however have at least 4 wires, Data +, Data -, Power and Ground. Test your cable with another data device, or try a slightly thicker cable.
