I had mine quit once, but the OD light was flashing, it was still under warranty so I took it to the Ford truck dealer close by. They said it was a speed sensor & that when this happens it is a no drive condition. Since the sensor was replaced it happened one more time & I stopped & shut her down & restarted & all was well. Hasn't happened again & its been over 2 years.
