I have a 95 Volvo 850 with 105,000 miles on it and I live at high altitude in Colorado. About two years ago it started giving me a problem. It would randomly shut off while driving. I will all of a sudden not be able to give it any gas and all the lights on the dash come on and the engine shuts off and then I’ll need to pull over. For a while it would start right back up again and it didn’t happen very often so I didn’t really address the problem. But in the last year it has happened much more frequently and now it has become an issue because it won’t start right back up again. Now I’ll have to leave it wherever it is for about an hour and then it will start back up again.
The fuel filter, fuel relay, spark plugs have all been replaced. I took it back to the mechanic and then he changed the crank sensor. This didn’t fix the problem. At this point I don’t want to keep taking it back to him to just pay him to keep guessing. What should I do? Any ideas of what the problem might be?
