My 99 F-350 With 7.3 Has Just Started To Shut Down Under Load,i Have Changed Fuel Filter And Added Fuel Conditioner But Still Shuts Down After Warm Up . No Check Engine Lite But Service Engine Soon Does Come On. Cam Sensor?

[mschn99]

your service engine soon light is your check engine light......and the fact that it does it only under load means there is a multitude of things it could be. cam sensors are usually not consistant.....they will just do it whenever....so first thing to do would be to get a hold of a code reader and get us the code, and from there we can get you pointed in the right way.

I HAVE A SCANNER AT MY SHOP BUT HOPE I DONT NEED WRECKER TO GET TO IT

[mschn99]

im not trying to sound sarcastic when saying this....so dont take it the wrong way, but first off, could the fuel quality be poor at the place you bought it at, and secondly, is there any chance you put gas in it??

[mschn99]

if the engine is already off, the service engine light will be on.....running right or not........just like before you start your truck

[mschn99]

oh, and have you checked your oil level???
