Worth checking error codes as a first step.

http://www.gt4dc.co.uk/info/howto/ecu/e ... _codes.htm

Fuel pump should be 12V ish or at idle / light load a resistor is swited in series which will drop it to about 8-10V

Have you recently disconnected the battery? If so, you need to take it for a decent drive for the ECU to re-learn idle point.
Also, check battery is holding voltage

If you have an immobiliser fitted, these are renowned for having a relay contact fail and intermittantly prevent running.

Also, have a look at the following thread, the ECU is under the dash behind the centre console, pull back the carpet that sticks up on each footwell to access. This is now a VERY common problem on RC & CS models - worth a look and if you find one or both capacitors has leaked it can be repaired by a local electronics place or I can do it. IMO worth changing them anyway before they damage the board (they only cost pennies).

One of the prime symptoms. If you don't have or know a decent electronics place locally I can do it remotely by post or I come down to Newquay fairly frequently if you're anywhere near there.
Once you have symptoms, there's normally tracks to repair / bridge as well as just replacing the capacitors.

If its from a later 185 it may work but keep the boot light and stay off boost.
