2001 Excursion 7.3 problems!

Ok so I just got this 7.3 Excursion with only 98K on it. Been using it around town for about a month with no issues until this week. I first noticed it when driving on the highway about 70mph and it started missing and losing power. Pulled over to the side of the road and it had a very rough idle. Turned it off and waited a little then it turn over and ran like nothing happened. About 10 mins later it was back. It did this for the whole day. Did some research and thought maybe it was the CPS. Changed it out with a FORD CPS and it ran great for a few days now its back, but worse. It will start out great then after about 20mins or so of drive time its acts up or when under heavy load. Last time it did it and I tried to pull the ICP plug to see if that may be the issue but no help at all.(yes there was some oil in the plug) Didn't change anything. Fuel filter looks good. I really don't want to bring it to the local stealership but I may not have a choice. NO CODES OR ANYTHING THING! Someone please help. Just tried it again and it runs fine no issues, but I dont want to get stuck again.

check your cps(cam positioning sensor) I had the same issue. Pulled out the Ford new rev and installed a sensor I purchased from a local INTERNATIONAL dealer went away for good. Good luck! Ps I now keep a spare CPS in my glovebox.

The UVC plugs can come loose under the VC..only way to check is pull the covers. ford has a kit that will keep this from happening again..
