I have a Cat C10 Engine. I started the truck and it started as normal and after about 30 seconds it sounded like the engine cut out but then it came back like normal. Later, I started to accelerate and the engine cut off. It was as if someone turned the ignition of. Once stopped, I started the truck and it sounded like it was starving for fuel for a couple seconds and then it started running smooth. I began to accelerate and I went about 20 miles and I lost throttle power and I could hear the engine dying down. I eased off on the shoulder of the interstate and I put the truck in neutral at about 20 mph and pressed the throttle and the engine came back running strong. This has me puzzled. Anyone had this to happen?
