Ducati 996 starting issue... advice required on how diagnose
Discussion
Gents, went to take my 996 out this morning and it fired up first time as usual.
I let it warm up for a bit while I put my gloves on etc. then I turned the lights on but before pulling away I stalled it. Not a problem but when I went to restart it everything was dead... literally nothing, no ignition lights or alarm beeping or anything. Does anyone have any clue what might be the problem? It is a brand new battery so that is not the issue, could it be a fuse or something that has blown? Can't be anything much as it went form being fine one second to nothing the next. Appreciate any thoughts on what might be the problem as I will try and fix it when I get home later, thanks!

Check the kill switch.. (I know, but it's been done a million times)
Stick a multimeter on the battery. If that's dead, then there's probably a charging problem.
If it isn't, then something else is inhibiting it from starting.. If it's not even turning over, I'd be looking at sidestand switches, kill switches and all that kind of stuff.

They are quite prone to the front battery terminal corroding (not sure why). With the vibes you can find that the connection is actually broken. Take the battery terminals off and clean/sand the contacts.
Try reaching through the vent in the right hand side fairing panel and pulling about the loom cable to the positive terminal (you can just get at it) and try again.
If not, could be a bad/corroded earth strap. If the battery has charge when you take it out, but the bike is dead with no lights or anything, these tend to be the most common things, unless there is a problem in the ignition barrel.

I'd second the "check the ignition relay" approach. My 848 Evo randomly stalled a couple of weeks ago, and whilst it would crank no problem at all, it wouldn't run.
On mine it was the coil relay, which also powers the fuel pump and injectors, but it is essentially the same problem... They do seem to be quite a common issue.
This was the relay for mine.... http://www.ebay.co.uk/itm/301072119214?_trksid=p20... but I think (*)they're the same for all Ducs

- definitely double check that though

The older bikes use a different relay, it's a 5-pin but SPST (although with 2 NC contacts), rather than a conventional SPDT 'changeover'. They are not as common but can be found at some motor factors or ebay for about £6-£7, however they're only about a pound more from Ducati.- definitely double check that though
Worth keeping a spare as they do tend to corrode leading to intermittent failure after a while.
I read this thread this morning, thought 'poor bugger, no idea but I've just paid £200 for a rewound stator on my 996 so I'm alright Jack'.
Then exactly this happened to me when I tried to leave the pub this evening. So I push-started. At the petrol station 15 miles later it started first time.

Classic ignition relay failure; nothing at all and then a few minutes later all OK again, once running usually OK.Then exactly this happened to me when I tried to leave the pub this evening. So I push-started. At the petrol station 15 miles later it started first time.
I had exactly the same on my 916.
Thanks for all replies, after I played with the battery connections this evening seems that everything is back to normal.. Must have just been a loose connection, I thought something to do with the datatool alarm but that seems ok now. Hope to get out on it over the weekend, must try and use it a bit more!
If you're looking online, this should do the job; http://www.ebay.co.uk/itm/0-727-32-12-VOLT-12V-MIN...
Note; you need 2x 87 terminals rather than an 87 and an 87a (changeover).
