This could be anything from an ignition issue to a clogged catalytic converter. If the converter is clogged you may have a fueling issue that caused it to break down prematurely. This would have to be addressed before replacing the cat that is if the cat is plugged. Now if you have an ignition issue this also could cause the cat to deteriorate quicker. Either way it sounds like your going to have to have a professional look at it. Now if your lucky it may just be a bad sensor. But the question is which one. Again this is money wisely spend if you leave this to a professional.

You probably have a bad governor pressure sensor and solenoid.The pressure sensor is what normally goes bad ,but from vast experience,i replace both of them together and change fluid and filter.

is commonly caused by a dirty automatic idle speed control valve and
throttle valve but always run a OBD2 (1996 and newer) or a OBD1 (1995
and older) fault code as well as the cleaning procedure. Buy a can of
throttle valve cleaner (do not use carburetor spray cleaner!) from
NAPA or Carquest (made by CRC chemicals) and spray it into the air
intake while the engine is running, use up about 1/2 the can, engine
will try to stall hold the speed up, shut it down and let it soak for
30 minutes, restart and blow out the remaining fluid, shut it down
and disconnect the negative battery cable for 5 Min's to reset the
base idle control
