It was running fine down the high way when the motor just cut out. Now when you crank it it idle rough and has a loud knocking sound. The motor will smooth out around 1500 rpm and higher. I only put 60 miles on my truck from the last time I filled up. I changed the cam sensor about 2 years ago. I was woundering if it could be that sensor going out or if I got bad fuel or if anybody else had this problem and it was something else. Thank you. Any help would be great!

a knock inside the motor? Not a good sign, can be a bad wrist in, or connecting rod bearing, crank journal, and it may be affecting the knock sensor, which will retard the timming.
