My 2003 K1200lt has this problem where It passes the self checks and low speed test fine but about 5-10 minutes after running the brake fail light starts 4x flashing and the warning light is steady on. The ABS continues to work for a few minutes and then stops working and brakes are manual. I replaced the battery and got real excited because everthing worked for about 45 minutes and started its bad business again. Its almost like the thing gets warmed up real good and then something causes the problem. Any ideas?
