Definitely read the warranty paperwork, especailly the fine print. Although my extended warranty wasn't an ESP, I did have a somewhat similar situation. Spun a bearing in the 2.5L @ 52k miles and an inspector came out to look at it. I'm friends with everyone at Ford and my Service Advisor told me about his meeting with the inspector. He said the motor was extremely clean and could tell that it wasn't because I neglected it. The reason my claim was denied was because I couldn't show "proof" that I had done regular maintenance(oil changes) to the motor. I would have had to shown receipts of professionally done oil changes, so me doing my own oil changes and showing them receipts of oil/filter purchases wasn't good enough. Might want to see how the warranty defines "abuse" in your case.
