Same problem, 98 V70 T5 with 162,000 miles. Recently stalled when rolling to a stop light. Restarted no problem. Again a few minutes later then nothing for a day or two. Intermittent problem over the past week or so, sometimes stalling or sputtering when driving on the freeway or surface streets. Replaced fuel filter. No help. I just replaced the fuel pump relay. So far, no stalling or other symptoms since replacement of the relay. I read on other boards that the fuel pump relay is a comomon fault for these symptoms. Cost was $40 and got part at local auto parts store. Five minute fix.
