EVSE Randomly Goes offline and Charges outside of the schedule

So I owned my OpenEVSE for a little over a year now, and about a half dozen times I've had this happen:
1. The OpenEVSE goes offline, it is no longer accessible via WiFi, I stop seeing status reports via MQTT
2. Sometime later, not knowing this, I plug in my vehicle. Charging starts immediately, despite the fact that it is outside of the configured schedule. However, instead of the configured 40A charging, it charges really slow, like 8A.
3. The screen Says "Ready, 40A" (no error, no indication it's charging)
4. I power cycle it, and everything is back to normal.
I thought it was somehow related to temperature, I had it happen twice in a week last week (one of our coldest weeks), and it happened 3 times in one week in July when it was hot). However, based on reported temps, it did not happen during the hottest part of the day, nor did it happen at the coldest part of the day.
Is this a known problem? The charging super slow seems like some weird backup/default method, does that indicate anything? Is there anything I can do to improve logging and help figure out what's happening?
