Default Re: loss of power, turning off/ restart engine fixes the problem

Had a similar issue. Lucky to have a scan gauge as there were no faults stored but i could monitor the boost pressure during the malfunction.
Observed the following scenario:
No boost pressure , ok voltage, outside air temperature 15C, intake air temperature 60C!
The intake air sensor was faulty and shutting down the boost pressure by way of the variable vane turbo charger opening the pitch angle.
$40 fix for me. Hope you are so lucky.

I just got back from the Dodge dealer, they did a scan ( none of the lights on the dashboard were on) and here are the results that they gave me.

"scanned found codes - 2511 - EGR single circuit short to ground, 5778 camshaft position sensor circuit open, 2043 camshaft position sensor circuit open or short --- possible wiring problem need further wiring diagnostic."

I am thinking most likely that there is a wire that is shortening. any suggestions on how to search for the problem would be appreciated.

Check harness around driver side motor mount and intake manifold.

I had a similar problem. I got a scan that showed low pressure in the fuel rail. They changed the filter and said it was VERY dirty. Based on info on this forum, a clogged filter may be the reason for the power loss. In any case, I now have a bit more power than I had, and the problem has not recurred.

My previous owner provided all the service records. It turns out the filter was in there for 40K miles. However, the problem happened after a fill up during which I left the engine running and the pump diesel pump was extremely slow. So, I might have picked up something during the fill up that clogged the filter.

Had same problem. Check engine light did not come on for a long time. Scan said bad Mass Air Flow Senser. Very expensive but be sure to use OEM one as after market have caused addition problems. Changed senser and runs like a new Sprinter. Smooth shifts, much higher RPM'S and good power on hills. 2003 3500 170WB ext.

The incoming fuel could also have stirred up crud that was already lying in the bottom of the tank, and that got sucked up since the engine was running.
If the engine had not been running, it may have settled back down before the flow started.
