Default O2 sensor code

Wondering if anyone has had this same issue. Over the weekend cruising down interstate bikes running like a dream, as I get off the exit ramp down shift into 5th coasting down the ramp the check engine light pops on. Bike is running perfect still no issues, I pull into a gas station and check the code and it pulls the rear o2 sensor p0152. I clear it and check the wiring for the sensors and all seems well, jump back on the bike and ride 300 miles between that day and night and it never comes back on. Yesterday I decided to ride to work 50 mile round trip, on the way home once again coasting to a red light the code comes back. During all this the bike seems to run the same.

Exhaust leak? Loose header bolt?
