Michael,
You are definitely not the only person who has been experience overheating problems with the 2005 Fisher Price motor. Take a look at these threads;

To summarize, these motors do not react well to stall conditions at 12V. We've limited them to 9.6V in test runs, and still had difficulties at stall and near stall conditions. We've now changed the application of the motor, to avoid running close to stall.
