Update:
software is KCS v2.1.9
I start "ping" from my laptop - A8 replay around 3 hour, but than "dies"(((
In same time A16S with KCS v2.2.2 works fine - i did not find no one "connection lost" for this time

Hi! power supply is 12v 5A with 2 battery
Red cable used to power on another ESP8266. Yesterday i remove this cable and power on ESP8266 by usb - with same result - connection lost...
Next i find KCS v2.2.2 and install it - so, it work more than 6 hours now, and connection is OK!
I will observe, but i hope the problem is solved.
Thank You!
