2000 Volvo S70 • 5 cylinder FWD Manual • 145,765 miles

My volvo will start an die. If I leave the key turned on it will turn over but not fire. If I turn the key off then try again it will start an die. It doesn't do it all the time. It seems to happen after I have driven to town and shut the car off an try to strat it when I come out of the store. If I wait 10 or 15 minutes it will start right up an run just fine. I have noticed a slight decrease in gas milage, maybe 2 mpg. I have been tring to figure this thing out since August. HELP PLEASE
