2002 Mercury Mountaineer "OD OFF", "CHECK TR

Hi, I am getting the following message. The engine went out 2ys ago and I am getting this message again. I took it in to the same Ford dealer to get it checked out and I was told the engine is going out again. I don't understand? How is this possible only after 2yrs of having it rebuilt? I am told it will cost me $3000 to get it rebuilt again as the warranty expired on the first rebuilt. Could this be a electrical issue? I hope it is, I don't have $3000 to get it serviced. I emailed ford company and was told they can not do anything about it. We have never driven anything but Ford because of our believe in "buying American" - it doesn't look like Ford will be in our future purchases.

Any help trouble shoot is greatly appreciated. Thanks!
