If Im not giving the bike throttle, it just switches off

[parsasm]

Hello,
I have a 2002 L9 which just had a service done about 3 weeks ago.
today i was just driving on the motorway for about 3 miles then when I came off the motorway and stopped at some lights the bike just switched off!
I switched it on again and when I don't give it revs it switched back off.
So I switched it back on again, kept some revs on it and drove it home, but whenever I put it in neutral or held clutch in the revs drop and switches off again.
I left the bike off when I got home for about 5 mins and now it's fully working again and not cutting out. But what's the issue?
Thanks

Turn the idle speed up.
It will be next to your right knee.

The idle is fine, the bike isn't having the problems today, it just happened once yesterday. Just driving along and as I came to a stop, every time it would drop revs and switch off.
I left it switched off for 5mins, switched it back on and all was well again.

could be a mixture problem, mine did it when the pilots were too rich, turn the 4 adjuster screws 1/4 turn counter clockwise and see if that helps.

Could be a bit of bad fuel?
