I am having an issue with my 98 S70 N/A. The car will sputter out and die while driving like its not getting any fuel to the engine. Once the car dies it will not start again for about an hour or so. When trying to start the car after it dies the fuel pump does not turn on but after the car sits with the keys out it will start up and run fine until it decides to have the same problem and leave me on the side of the road.

I have replaced the MAF (had a code from the ECU), the fuel pump fuse (in the main fuse box), the fuel pump relay (Fuse #103) and also the fuel pump itself. The issue has a mind of its own on when it wants to occur. I can't do anything to recreate the problem while I have the car home in the garage. I have tried to cycle the key from the off and on to see if I can hear if the fuel pump comes on which it does every time, I can drive it without any issues until it starts to sputter, choke out and die. Once this happens the fuel pump does not turn back on until the car sits for some time.

Any ideas? Please help!!
