KBZN CTD now all of sudden

All of sudden I am getting ctd at KBZN, it is my home town airport so I fly here often. Never had a problem before. It happens when taxing to runway 12 or shortly after take off. Also taxing to runway 12 it almost like I getting slowed down for no reason. Can anyone ckeck and see if you have same problem or if it just me, Thanks.
