7.3 Ignition Cut Out
My 99 F250 SD, CC, 7.3, has 115,000 miles. This morning on my way home from work as I was going down the freeway my ignition cut out on me about 4 times. First time at about 70 mph the ignition just cut of and then when I put it in neutral and it slowed to about 50 mph it came back on. The next couple of times I pulled off the freeway and stopped. Then put it in neutral, then turned the ignition off and then on it started. I was able to make it home without any further stalls.
What could this be? Cam positioning sensor?
Appreciate all assistance.

Have you ever replaced the CPS? That's a real good bet because that is exactly what they do. I was lucky enough to have mine go on a rural road at about 35 mph. Nursed it home without a clue what was wrong until I did a search right here at FTE.

About the cheapest is ebay. Do a search for it. The item is physically located on the front of the engine , passenger side, just above the harmonic balancer. Do a search here for particulars on it. Tons of info.

Sorry so late getting back to the post. Got the new CPS and it is back on the road.
Thanks for all the help.
Now I just need to get my fuel mileage back up. Right now I am getting 15.3 city and highway running just under 2000 RPM.
