Checking for Vacuum leaks is sound advice. Does the vehicle sputter, bump, or hesitate? Or is it just suddenly wimpy?
Check regular maintenance stuff -- spark plugs, rotor, air cleaner, fuel filter, et cetera...
Check for a plugged catalytic converter.
Check timing.
Check fuel system. (Plugged injectors?) Many shops can circulate a potent solvent through your fuel system and inspect the injectors for a few hundred dollars. Usually makes a big difference in performance.
Still no power? Have your cylinders compression tested. (Yikes)
