My 2002 7.3 will go dead when driving then not start up until after it has sat for a good hour. Then only run for about 10 minutes before dying again. The truck will stay running if left in park idling. It only stalls when it is driving.

I replaced the Camshaft Position Sensor and Alternator with Genuine Motorcraft parts. My next assumption is the ICP Sensor? Maybe.

I do have a kill switch on the truck that I thought might be loose--but I'm not sure. Any ideas?

 

Have you tested to determine whether you are missing spark or fuel? That is where I would start. That first test is critical to determining what's wrong with the truck.

 

The 7.3 powerstroke does not have spark plugs. Checking the fuel is why I'm asking about the ICP Sensor.

 

First, bypass the kill switch and see if it is the problem.
