While driving the truck will go to reduced engine power. I can stop, turn the key off and restart within a few seconds. It will then run fine, sometimes for a few miles, sometimes for weeks. Some times it will clear the engine hours, sometimes it won't. Also sometimes the check engine light will come on, sometimes it does not. What could be the cause of this? I have not had the codes read yet.

have replaced the camshaft ,crankshaft sensors , just replaced the fuel pressure regulator ,still will not accelerate .have to push so very easy to get go. it takes a while to get too top speed.if you mash the gas too hard sometimes you have to start all over again .
