2000 Volvo S70 Starts then dies. Seems to do it more often if the engine is warm. Wait 10 minutes and it starts and runs fine.

Fuel pumps are common on these cars. Its a hard fault to duplicate with a gauge because they rarely die at idle! I would still connect a gauge and see pressures though, see what happens to them when it starts to die (if it will at idle). 99/100 times you need to replace the fuel pump, and fuel pump relay. The relay overexcites and burns out your fuel pump. As long as you dont have AWD its not a difficult job, if its AWD then you have to lower the whole back end of the car (springs, diff, AOC....) to lower the tank enough to get to the pump. Make sure that you align the pump correctly or you will have a false fuel level reading.
