Check Engine Light On problems of the 1999 Ford F-350

I am the owner of a 1999 Ford F-350 diesel super duty truck with duels. While driving, the check engine light will come on intermittently. When this happens, the truck will not accelerate. It's still running, but you can't go any where. Pressing the gas pedal is useless. Sometimes the light will go off and acceleration is restored. Other times, I have to steer the truck over to the side of the road and either put the truck in park which will sometimes make the check engine symbol disappear or turn the truck off and restart it. This makes for a very dangerous situation where I am at risk of being rear-ended. I am very fortunate not to have been in an accident yet and pray I won't be. Please help or point me in the right direction to get help! thank you!.

The left rear wheel separated from the vehicle, which caused the vehicle jerk foward. The consumer requested an 03 vehicle or reimbursement for the incidental expenses. After the purchase of the vehicle, the manual, lockable hub(s) began to fail. The dealer convinced the consumer(s) to purchase 8 ply tires, but this didn't reduce the noise or hub problems, the consumer also experienced acceleration problem's. The dealer couldn't find the problem. The engine idled rough and the engine light had come on. A bad cam sensor was found, and a sound had come from the fuel pump. An adapter to the metal plate was built in, extending from the underdash, to the firewall, to provide a better ground system. Scc.
