After 5-10 seconds after starting sometimes the engines shuts down. A couple times while coasting. Never during higher rpms. A couple times it hesitated at 30 mph. At these times I get the emissions warning light. A free computer check at Autozone reviews no codes. Map sensor? This is a 7.3 2002.
Thanks in advance

Couple things I have heard mentioned b4 are the Glow plug relay, Crank shaft sensor, orTorque converter lock up

 

How often does the stall occur and at what temps, or is it just on 'initial' start? Does it restart imediately afterwards on a stall? Miles on the truck?

CMP(Cam PositionSensor) failures are pretty common on the 7.3.. If the sensor fails you'll loose the tach signal.. Without a tach signal the IDM won't fire the injectors. If the engine doesn't restart right off, look at the tach while cranking and see if you see aneedle movement/bounce.. Even with a scan tool sometmes a bad CMP/circuit can be hard to diagnose.. If its the original, areplacement wouldn't hurt.. The DTC would be handy to have for a more clear direction, but with their given history of problems probably the first place I'd look.. Not the only thing that can cause a stall though, or a hard start..

 

Does it just cut out when driving down the road or sound like it skips a beat every now and then? We replaced many of those cam sensors in those things.I have an International with the same motor & did mine twice in 75,000 miles. Hayapower is probably right. We also found they have had problems with the valve cover gaskets. The wiring inside them goes bad & they do something similar to what we're talking about, but more of an intermittent misfire or running real rough.

 

i'd go with the camshaft position sensor
