Intermitent spanner light and cutting out

2005 Vauxhall Signum 2.0 dti
Car: Vauxhall Signum
Year: 2005
Variant: 2.0 dti
Categories: Running Rough, Starting & Power Loss
car will run fine for a few weeks then it will start idling poorly, shortly there after spanner light will come on, accelerator pedal will become unresponsive and the car will keep dieing on ignation. can keep starting the car for 10 to 20 mins and problem normally goes away.
Took to the garage and diagnostic test showed problem with accelerator pedal sensor, had replaced but problem still persists.
Any ideas ????
