I own a 2005 Nissan Pathfinder which hesitates between 35 to 40 mph and sometimes around 60 mph as if to cut off (running rough). When I take my foot off of the gas pedal the engine runs smoothly. There is no check engine light on but I can pull diagnostic code B0F59. I've tried several automotive shops and looked on line to find out what this code means with no luck. Can any one tell me what this means?

You scanner is porbably not compatible with your Pathfinder. "Bxxxx" codes are related to the body control (air bag, lights) and will not cause any driveavility problems. The B0F59 is not listed in the Factory Service Manual.

B0F59 this is not a definition at all. "B" in the front is Body control, the second number is  0 which stands for SAE OBD 2, the next will be the network communication which you have is a "F" there no allocation for this and the second digit 59  are areas , these are seat belt codes, You basically have a airbag codes, which is not the problem with the vehicle, This is also a defintion for window operating system,Your vehicle at some time had a recall for a ECM relay replacement that can cause arcing and stalling, A failing ECM relay can cause exactly what you are experiencing and can also code this up, Recall # PC068 titled ECM control module relay replacement, and Recall # 10V517000 ECM relay replacement. Above all else replace the ECM relay.
