My V70 D5 2003 did the same for a long time prior to the in tank fuel pump giving up which in the end prevented the engine from starting but apparently they can fail intermittantly for a long time before finally stopping altogether and this put it into limp mode when accelerating . Also had a long standing power loss problem ( which also caused limp mode ) which I still suspect was a second problem which was never diagnosed despite checking nearly everything as this continued for a while after changing the electric pump , it may well have been a bad electrical connector which after jiggling all the critical connectors and running the car with the maf unplugged for a few miles seems to have cleared itself . The car has had no major component /pipes/sensors replaced since new other than the pump , its on 141k miles now .
