Hi,

Does the check engine light stay on when it is running? Also, does it stall or not restart easily?

The idea that you lose power as mentioned leads me to think you may have a partially plugged catalytic converter,

Do me a favor. Take a look through this link and let me know if you feel it mirrors anything you experience:

Let me know your thoughts.

Take care,

Joe
