I have a similar issue, so allow me to add details, perhaps someone with knowledge might spot the reason:
So I have 5 NodeMCUs reading temperatures from a DS18B20 temperature sensor and send this reading every 500 ms via MQTT to mySQL db.
When I reset/power down and up the readings are sent and logged just fine.
Then the problem:
For no reason at no specific frequency (from 1 hour to 30 hours) the NodeMCU will just stop sending readings.
I can see it when I monitor traffic via MQTT and missing entries in the db.
Sometimes a NodeMCU will after say another 20 hours start to send readings but die again.
I am using more than one APs, but they are being used by other devices without issues
