Just something to check.
Solara's thoughts of the sensor wire or board might be right but I've run sensorless several times (mostly not on purpose) and never had that issue. I'm thinking the servo or possibly a connection that is slightly less than perfect somewhere. Check the bullet connections and all solder joints for a good connection too.
Let us know what you find (if you find it)
