I thought I had a bad seat bar sensor when the problem started. Occasionally and randomly the interlock would fall out. I replaced the seat bar sensor with a cheap sensor. The problem seemed to get worse. I replaced the plug that connects to the sensor thinking it was not making good connection, but that didn't work. Replaced cheap sensor with bobcat brand sensor, still no good. I have cleaned and reconnected every ground on the machine. The machine may run for 30 minutes without a problem or may not last a minute. It will throw every code in the book for a minute then clear. Any help would be appreciated.
