Hard start

Been driving my 2001 f250 7.3 4x4 with no problems then started noticing it lacking power so I changed fuel filter and air filter. After a week goes by I was at work and I was leaving to come home so I started truck to let warm up and it cranked longer than normal but started. Let run about 10 minutes idle nicely when I punched it it bogged down and had no power never died. I idled over into parking lot and power came so I took off again loss all power again, still never died. Got it right back to my work sat there a bit and tried again this time I took it easy and was able to get my truck home 30 so miles. When I got home I ran codes p1211 came up for the icp sensor I changed it did not change anything still had same problem. This was a Saturday afternoon to evening issue. So sunday I played around with it just checking out info online and test driving it seem to run ok but still lacking power. Let it sit till Monday I went out to start it had to cycle key 3 time before it started idle nicely then died would not restart changed ipr valve nothing changed cam sensor nothing changed some how 10 quarts low in oil just changed dec. 30th don't know ? Now will start if I pump throttle and has all its power back any ideas?

As you know, your truck has to have oil to run the injectors. 10 quarts in a month is a huge loss, so that has to be dealt with. Do you know where it is leaking?

Once you refilled it, do you have a gauge to monitor your fuel pressure? When you open the drain on your fuel filter does fuel pour out? Sounds like your engine is not getting fuel. Fuel pump may be dying or fuel line is blocked in tank would be two possibilities.
