My Miata developed what sounds like the same problem as yours at 65000 miles.
I replaced the plugs, air and fuel filters, and it alleviated it, but didn't
make the problem go away.  The car ran fine when cold, but would run a little
rough when hot.  Fearing a fuel injection problem, I had the dealer diagnose
it.  It turned out to be the spark plug wires.  These are pretty expensive,
so I didn't replace them when I replaced the plugs, thinking that wires
rarely cause problems (at least in my older British cars!).  The dealer wanted
something like $70 for a set.  I got a set of NGK pre-cut to fit a Miata for
$50 thru my favorite Beck-Arnley dealer.  You can probably make them for
less.
