Check the cats new plugs an wires
It seems I have more questions that need to be answered. Have you got any on board diagnostic codes. If not you need to hook up a code reader to see if it is storing any codes that will let you to the problem. Most generally the lose of power is related to the timing and is controlled by the O2 sensors. another this is the mass air flow sensor located on the air intake tube next to the air filter. I hope this has been of some help. Good Luck
One other thing, you may want to check the fuel pressure. It the fuel pump is failing, you will lose power.

SOURCE: a smell like burning wires when l go up a hill
hello drk...the only time you smell this is when the engine is under a load? Does is seem to be coming from the a/c vents? Any smoke? I've never heard this complaint on the 2005 6.0 powerstroke. A strong coolant or sulphur smell is what most owners report. Could you give a little more detail please?

Coil pack should in the front top of motor, with engine running remove one spark plug wire at a time from coil pack ( careful not to get shock ) they should all have spark, if one don't replace coil pack.
I would suggest you run a compression check on this engine and also have the coolant recovery tank tested for the presence of combustion gases with a gas analyzer, any gases would indicate a leaking head gasket. Any engine cylinder that is lower than 5% of the highest reading cylinder in pounds per square inch has a problem like a scored cylinder or leaking intake or exhaust valve seat.

sounds like either a vacuum leak (check the bottom of the "tomatoe juice can" for starters) or a bad or plugged egr valve or egr solenoid.
check engine lite refers to emissions probs only...most likely egr or vac leak. Had the same prob on my 95 5.0 f150...needed new can and egr valve.
