Power drops, and high backpedal resistance

[benzy]

I have a cannondale contro-e with a Bosch Performance Speed motor and Intuvia controller. About 1050 battery hours and 6k miles.

I havent ridden my bike for a month. Back on it this week I am experiencing power drops. The intuvia display stays powered on but the pedal assist cuts out for a fraction of a second multiple times during the ride. The power meter on the display responds in kind, dropping briefly.

I've cleaned all contacts on the battery and Intuvia (they were already in good shape), tightened the battery mount nice and secure, and USB charged the Intuvia since I read that somewhere. No dice.

One observation is the freewheel/backpedal motion is tighter than I remember. Seems there is an exorbitant amount of resistance. I am not sure if it's my mind playing tricks, but I remember there being a small amount of resistance but smooth. Assume there is similar resistance pedaling forward. Maybe related?

Any idea what's going on?

Regards,
Benzy

Want to bump this. Can I at least give some feedback if your Bosch motor has an inordinate amount of resistance when moving the cranks backwards? I remember the cranks moving much more freely.

No pressure pedaling backwards on my Haibike. No codes on the display? Magnet lined up with the sensor on the spoke? What kind of voltage on the battery? (Actual voltage not a bar on the display.)

Same thing with my Moustache Open XRoad 5, all is good.
