Hunting revs and a one off cut out

Hi guys,
I am the proud owner of a k5 gsxr 750 which I love dearly, it has a blue flame exhaust with no other mods.
I find when on idle the revs hunt for a better way of putting it and on a recent ride had the engine cut out under 3500 revs, no spluttering or coughing just immediate cut out.
Did what a usual bloke would do and ragged it down the motorway after which it appears to have returned to normal.
Any ideas please as to the cause? Also are fuel injection cleaning additives any good?
Thanks in advance for any advice.
