Answer
Brad,

I would check the tune of the engine.  That is, the spark plugs are new as well as the wires, cap and rotor.  Also, the fuel filter is good and you have good gas, as in premium along with a fuel treatment and a clean air filter.  After that check the timing and that the throttle body is clean.  Check these out and email me back with what you discover after you have done a complete tune up as described above.
