Reset the ECU.. (disconnect battery, press brake pedal 10 secs)

go for a drive... see if that is any better..
check condition of plugs, leads, rotor arm and dizzy cap.

Well, there ya go... glad it's sorted..

could have been a bit of crud in the pipes, and a good blat has cleared it..

Keep your eye on it, if it happens again, clean the fuel lines and filters..

In the meantime, use a good amount of injector cleaner in the tank..
