Bike occasionally cutting out

Just a quick post to see if anybody has any advice for me.
Bike is a K5n , about 2-3 weeks ago after i'd cleaned the bike took it for a ride and everything was ok ,the next day however commuting to work the bike just cut out on me ,no warning or anything the FI light was flashing so pulled over turned ignition off and back on and bike started normally . It did this about 4 times on journey but seemed ok on the return leg . My problem is it keeps doing this every now and then ,probably about once or twice a fortnight ,every time is the same engine cuts out no warning FI light flashing i'm at a loss . Think i saw a post something similar but can't seem to find it ,any help greatly appreciated .
