Okay I take great care of both of my 240's . I drive about 100 miles per day stop and go( I'm in food sales). Anyway driving my 91 wagon about 3 weeks ago and I coudl feel it loosing power and getting "weaker and weaker" it died on me and I restarted and it died out again. Man in car behind me help me push into parking lot. I called AAA to have towed to my Volvo guy. Anyway as I was waiting about 30 min later I tried to start it and it did start right up.So I decided to make it to my shop on my own. Well about 5 miles down the road it did the same thing. So we towed we ended up changing fuel filter and pump since they were orginal. Picked up 2 days later and it did the same thing again. Had towed to him again . He driove next day and said he couldn;t find anything wrong? Said he changed or did everything that may cause it to loose power and die? Well I took it and it seemed fine till a week later today. I write this from side of road in shade waiting in AAA. What could be causing this? I'm tired of being told nothing is wrong or maybe I used some bad gas? Anyone have any ideas?? Thanks!!
