Cam position sensor is not intermittent, when it goes bad the engine does not restart. Think about torque converter or injection control pressure sensor issues as a cause for the stalling

After going thru 3 or 4 cam position sensors i can guarantee you that they will usually restart after cooling down and then probably run real stupid like, or may run fine and then **** out again without warning. OOOOOOOr, my 99 was different than all the rest of them. :W

My Dad's 99 F350 smoked a cylinder going over Raton Pass 500miles after changing the coolant with no additive . Was still in warranty and Ford fixed it.
Also Bilstein 4600 are great for us.

I had a 2000 Excursion and a 2000 E350, both with the 7.3. It's a great engine. One vulnerability, which has already been noted, is the Cam Position Sensor (CPS) that is mounted on the front passenger side of the engine. Usually when these fail, the engine will usually start and run for about 5 seconds and then shut down. I also had problems with the wiring harness that connected to the CPS and this could be causing an intermittent problem. I also had issues with the Excursion with the wiring harness to the injectors under the rocker cover rubbing and shorting out.

You might be time and money ahead to have a qualified diesel mechanic check it out and make any repairs. It's a good truck and would be worth the investment.

Shocks - Put Bilsteins on it and you won't have to do it again.

There are lots of oil filters out there, many of them cheaply made. When I took delivery of my 2013 6.7, the service manager told me to always use Ford oil filters, even if I changed the oil myself. Also air filters. Diesels pull lots of air through an air filter and cheap ones can deform. Don't want to pay dealer prices ? Amazon is your friend.

X2 on the cam sensor, when they go the truck won't start. And carry a spare, and a 10MM wrench or socket to change,

Put a 6.0 trans cooler on it.

I forgot about that... Good advice.

Ditto on the cam position sensor. There is a recall and Ford will replace it for free. I keep a spare in the glove box.

Change the fuel filter every other oil change. Oil changes at 7500 miles, it holds 4 gallons. I use Motorcraft filters. I also keep a spare filter behind the back seat just in case I get bad fuel, has not happened but I stay ready.

Shocks, I got from NAPA, probably not as good as the originals.

Brake pads, I got 120,000 miles out of the originals on the front, replaced with Motorcraft from Ford dealer and still on the second set.

It would probably help to give it a treatment of Diesel Kleen fuel additive right after the filter change. That may help with shutting off, can't hurt.

The engine oil actually fires the injectors, I know mine has more power immediately after an oil change. I use Rotella.

Do not turn up the power too much, the 7.3 can make plenty but the 4R100 transmission is not able to handle much over stock. Do change the fluid and filter, do not flush. Mine has a drain plug on the transmission pan.

[Dave_H_M]

they recalled the 7.3's to replace the cam sensor.

If that has not been done the cam position sensor is a good bet on the staling.

I kept a spare in the glove box on mine.
