Hi there if the fuel pump fuse is blown your pump in the tank has gone causing your main pump to work over time and over heat .My wifes car did the same thing .You wont notice much till your low on fuel then it goes haywire as the small in tank pump cant deliver to the main pump.Simple job but a real problem for a non volvo mechanic to figure out .
The main pump can fail in this way even if the in-tank pump is good. The one on a friend's 240 did several years ago, it was pulling so much current the relay socket melted down.
