Today, I started the truck, ('99 SuperDuty PSD 7.3) let it warm up about
3mins, and started up the road at a normal (easy) pace. Started up a slight incline, and suddenly lost most of the power, the truck started slowing down, the service engine soon light came on, and the truck wouldn't accelerate by mashing the pedal. It didn't shut down, just acted like a gas motor when it's choked too much. This all happened in about a 25-30 second time frame. I put it up in Neutral, let it settle down to idle, put it back in Drive, and accelerated like nothing had happened, and in about 15 more seconds, the service engine soon light went off. I had no other problems with it today, subsequently driving about 90 miles.Weird.
Anybody have a similar experience, or have an idea as to why?
CPS?
