E39 528i Sport Engine Trouble

[qualitydobbers]

Had some problems with starting my 528i up last night after it had been left stood for an hour whilst I had a session in the gym. It's only the second time it's happened since i've had the car in a couple of months but what seems to happen is that the engine takes a while to turn over after it has been used and then left stood for a short while (usually around an hour) and when it is eventually running, it kind of stutters as it's accelerating and seems to mis-fire, not running at full power. Also, when the revs drop whilst i'm driving at low speeds, the engine just cuts out.
Just wondered whether anyone else had experienced similar problems with their motors? I undertand that, after reading on the parkers website, some of the earlier 2.8 engines had problems with sticky valves although mine is a 1999 model 528i Sport and wouldn't really be classed as an early E39 so is it something else?
Any advice is much appreciated, thanks.

off the subject but what kind of headlights do you have and how much were they?

They're just standard 5 series lights, they came with the car when I bought it
