Hello, I copied and pasted this issue from a post from years ago because it is the exact problem I have and no one answered back then. 2019 Surface 604 colt. Any help would be great, thank you.

Lately I've encountered an intermittent power loss issue. Symptoms:

- complete loss of power from the motor
- wrench symbol appears on the display. Manual says this is a 'fault' indicator
- occasionally a '30' appears in the speed display
- battery level flashes zero state of charge then returns to normal
- can't get any power/assist back from the motor unless I stop and power cycle the bike
- seems to happen at random times/ loads (torque)/ speeds/ PAS levels/ ambient temperatures

I've checked the battery connectors but they seem normal. Anyone else experiencing this problem?? For those who are experienced with Bafang equipment anything else I should check?
