I have the very same problem the truck runs fine and then suddenly loss of power and the EDC light comes on if I then switch the key on off an ON again it runs fine. I have replaced the control unit had the injectors tested and calibrated changed the hp pump but got it back today and did the same thing. I noticed that when it labours a bit in a high gear just before or as the turbo boosts the the power cut and the EDS comes on. I have spent a fortune and the problem does not seem to go away

Could anyone please help or make suggestions on what I need to check and in what sequence
Thanks

Doesn't look like this thread was resolved. Shame not to have the outcome.

You might also try the diesel section if you don't get any info here. Be great if you could fill out your profile with vehicle details too.
