Stalling

[RCK]

2000 7.3 with about 90,000 miles. This seems to happen more when the temperature outside is below 40 degrees or so....but has happened more and more on warm days also. Also happens with engine warm or cold.

While driving the engine will stall out. It seems to come back up to power when you ease up on the accelerator then depress it gently. Sometimes all the dash lights come on then go right out again. Occasionally the engine will flat out die...but most times just temporarily loses power.

Have had it to the dealer recently and they can't find any problems....though they know that it is doing it from test drives.

Any help would be very much appreciated!

How do your Fuel filters look. I dont know that thats it but its as good a starting place as any

Thanks Ryan....I should have probably said that this truck is stock, has been 100% dealer maintained and all maintenance on time as recommended. It just came out of the dealers shop where I took it specifically for this problem. They did in fact change the filters, they also replaced the Glow Plug Relay and told me the problem was solved. Sadly....it isn't.

I am definitely no motor head (wished I was) but I keep thinking it is a Cam Position Indicator, based strictly on reading symptoms similar to mine from others.

welcome to the org, check your TPS (throttle position sensor) it could also cause symptoms you describe

For anyone who checks this thread in the future to solve a similar problem....turns out it was the alternator. The alternator was functioning to a limited degree, but was definitely on it's way out. After the alternator was changed out we haven't had a single hiccup. Hope this helps someone down the road.
