Engine shut down on me in the middle of a busy road for no reason!?
I was pulling my first big load today with my truck. I have about 3200 miles on her. Pulled the 10,000lb forklift on a trailer just fine...until I tried to give it the beans going up a small hill and the truck pulled but shuttered to the point where my passengers even noticed it. only mods I have are the AFE and the MP-8, which I had turned up at the time. The shuttering felt like it came from the tranny and I felt like I should let off. Again, it was only noticible at more than half throttle. The BIG problem I had today though was later in the day when I was on a busy 4 lane road just about to go up a small hill and the truck (engine) just died. Drove perfectly normal one minute and just plain cut out the next. As I was coasting with no power and no way to get over ot the curb lane my first thought was to look for warning lights or hot temps but the dash showed nothing was wrong. My second thought was that I had run out of DEF and it was going into idle mode but it didn't even idle. It was just plain off. Had electric but no motor. As I came to a stop I checked the DEF fluid level in the menu and it said under half full but that's it. I don't belive this to be the problem. SO anyway, I put it in park, turned the key off, and tried to start it and luckily it fired right up and I got moving again. Was fine after that. I also noticed later that day that I was getting that popping or chuch chuch chuch sound that I have been noticing since I put on the AFE. Still does that randomly oncein a while and I can't make it do it at will. Usually happens just as I let off the throttle or just when I am starting to give it very light throttle. Mostly when letting off lightly though. Any thoughts on any of this? Going to go to dealer with it soon for oil change and to have them check it out. I am mostly concerned about the truck leaving me stranded in the middle of a busy road with a load on ....in the middle of a hill. Was not a fun experience. WTH?
