It sounds like a dirty shut-off solenoid on the injection pump. Thaqt also suggests dirty injectors too. Try a bottle of this with an Italian decoke combined with several switch off/restart (not while you're driving!) operations.

Should improve power, economy and hopefully sort that sticky IP solenoid!
