Hi, we got problems like this with some "abused" ESP8266 (reprogrammed many times). As the applications, number of timer and enconder interrupts are very demanding, the WiFi stack lose time slots and fail starting retransmission that degenerate and crash the MCU. Please, just program a fresh ESP8266 with exactly the same code to check that is not this issue. If you want to keep current ESP8266, relax the loop interval and timer interrupt delay, to allow WiFi stack to recover.
