Loss of power
 

Hey everyone, I'm having a problem with my 05 rx8 with 43000 miles. Searched around and couldn't really find an answer. I started my car up last night after work to find that it had a huge power loss. I was able to get to about 15 mph in first and second gear after 30 seconds I would say. It started up just fine this morning and revs regularly for about 10 seconds and then bogs down. Coils, wires, and plugs have all been changed within the year. Any help would be greatly appreciated. Thanks guys

Could be a clogged cat.
