You've got a vacuum leak. Actually happens often when changing the oil on diesels (you do have a diesel?).
The lines get knocked. The fuel shut off is a diaphram that goes into the fuel injection pump. It sounds like you are loosing main vacuum.
Look in the area of your oil filter housing .... check each line very very carefully. Track the ones that go into the multi-group connectors. Push these connectors around at their junctions and see if there is a split.
Tells us your model and year.
