Hi , my 95' volvo 850 turbo had same problem like yours. But very strange it most happen while the weather & car is hot ( maybe air temp > 30oC , in Taiwan , very humid ).
I had replace the mass air flow sensor ( expansive part , I bought from Bosch distributor for cheaper , about 200 USD ) , the car run much better for months . recently the problem back again .
I had try to verify the oxygen sensor , but seems it is ok but somethings engine error code 2-3-1 happen.
You may also check the mass air flow sensor . And I may back to check my fuel pump stuffs...
