    My 98 Legacy AWD wants to die after it’s been running for about 30
    minutes. It runs fine when it’s first started but then out of the blue
    it just starts chugging. I replaced the plugs and wires, could it be
    the catalytic converter?

  2. I suppose a LOT of things 'could' be the problem in a '98 .

    You don't mention any check engine light/OBDII codes . If the light is
    not on, I suppose the Engine Temp. Sensor could be bad. Basically
    keeping the car in 'choke' mode even after it has warmed up. That may
    not throw a code/light the CEL.
