I have a 2005 Honda CBR 600RR, it will only stay running if i hold the start button down,
As soon as I let off start button the bike dies, What could it be.

What's the history on the bike? Has it been sitting in storage? Has anyone hacked up the wiring harness? Have you tried to run it on starter fluid to see if it will stay running longer?

Post a short video of the problem. There are a number of possibilities so give us some more info to try and narrow it down.

Does dash & lights turn on when you turn key to ON?
Do you hear fuel-pump prime for 3-sec?
