Miata cuts off

Dear Tom and Ray,

I am having an annoying problem with my 2000 Miata. Once or twice per day, my engine will cut off while driving. This problem began about 4 days ago. I notice that it seems to cut out while idleing or when i slow down to make a turn. The engine does seem to flutter during low speeds, and it just doesn’t seem to have that same “get up and go” attitude that i’m used to. There’s no ingine light warning, and besides the problem mentioned, there are no other problems. A friend suggested i replace the fuel filter, but he also misidentified another engine part as the filter itself. I figure i will go to the experts and get an “intelligent opinion”! Thanks for all your help. The show’s great!!
