I have had the same issue. Luckly I still fell under Ford's warranty. The service guy at Ford kinda gave me a hard time with it but, I thought it was the Cam sensor; showed same symptoms. But the service guy said it was the PCM. He swapped it out and said he would just write down faulty PCM when he sent it to Ford. Oh, and they also changed out my Cam sensor. So I guess I'll never know. He tried telling me it was the Evolution that did it. Edge said they would refund any money I had spent. Anyway long story short I did put the thing back in and had no problems so far. The actual Powerstroke tech said he wouldn't worry about it and left it at that. Its been over a year now.
