Sounds electrical. If you don't have the manual for it, you might want to try Volvo blog websites and ask the members; it might be directly related.

Re Cutting out while driving; had this problem with my 93 Volvo 940. Possibly a fuel pump relay, a common problem, solder cracks in the relay. It can be dismantled and fixed, but it's probably easier to just buy a new replacement relay.
