Check your ground connections, Fuel filter, catalytic converter.  It
sounds like a restriction either in the fuel system (filter) or in the
cat (exhaust) that is choking off your power.  Is this something that
just happened one day or has it been gradually coming on?  A bad tank of
gas can happen.  If none of these helps try unplugging the oxygen sensor
and see if it runs better that way.

Hope this helps,
