Intermittant fault... Engine dies like it runs out of fuel.
Discussion
Bump to an old topic, having similar issues on my CBR600F 2003 so injected.
Cut out once (first time) on the reserve tank so filled immediately, now doing it every 3 miles or so, always under constant throttle, lowish rev's. Bike feels like it's running out of fuel, starts dieing then flashes the red light and cuts out. I am always able to just hold the clutch in and restart immediately.
Is it likely to be the breather?
Is it an easy thing to access/check?

I think on this occasion mine turned out to be a fuel pump contact which was failing. I speculated it was happy a lot of the time with a vacuum but just every now and again this wasn't enough. I would be very doubtful you have the same set up on your injection CBR.Cut out once (first time) on the reserve tank so filled immediately, now doing it every 3 miles or so, always under constant throttle, lowish rev's.

If you're getting flashing lights however that would be your starting point in a diagnosis? If it's flashing there could be a code somewhere.
Which light is flashing by the way?

Thanks, no flashing lights, phrased it a little poorly - just as it dies the red light comes on and stays on until I can get it re-started.
It's running very rough, backfiring, misfiring etc. Strangely it gets worse and worse until it cuts out, when restarted its 100% better until it starts getting progressively worse again. Seems to be caused/exaggerated when accelerating from lower rev's

You have a basic diagnostic system, so it's worth knowing what it covers.
Try and replicate the fault it on it's stand. When it dies re-start with the fuel cap open, see if it helps.
Take the tank off and check the breathers aren't kinked. It should be obvious.
Then I'd be looking at testing the fuel pump, but that's very speculative!
This being a Honda I would be confirming the battery is charging correctly with a voltmeter even if the problem seems unrelated.
Hopefully someone more enlightened can help further.

I had the same kind of problem on my CBR600F (1998 if it matters). Problem was "breather" to the petrol tank - as the fuel was used up, negative pressure built up and starved the engine.
In my case I overfilled the tank which caused the problem (think the air comes in through the cap and a high fuel level prevented this somehow?). Anyway, couldn't restart the thing for love or money, opened the tank to check I didn't put diesel in by mistake. Tried it again, and it started straight up because I'd equalised the pressure.

Thanks guys
Interesting on the over-fill comment - When it first happened I was on reserve and thought I'd run out of fuel so pulled in a brimmed it. Thing is the tank hasn't been off the bike in my ownership (400 miles) and I'm not sure if t had been any time soon - just started randomly on Friday
