Cam shaft position sensor. Had this same issue on my 02 Excursion. There was actually a recall on it. Once it was replaced have had no issues.
This may be the culprit but I recall it being the crank positions sensor. Even though my truck is a GM, I had the same problem 2 years ago with my 2002 GMC. My truck had around 70,000 on it when it happened. Doing some research, the issue happens around that mileage and the problems were documented on line in 2006-7. The low mile trucks have the issue later in life.
The service department at our local GM dealer didn’t know what was happening as the truck did not throw any codes. I ended up telling them the problem and told them to order it. They were reluctant as it cost $500 but I knew that was the issue. It’s worked fine ever since.
