Sounds like fuel starvation or Idle Air Control. I found this

Reader query: Triumph Daytona 955i ignition problems

I have a 1999 Triumph Daytona 955i. It refuses to tick over when started from cold. After a couple of miles down the road, it seems fine. If I restart it before it gets cold it's OK. If I leave it longer than maybe an hour then the same problem occurs.

It sounds like it's running extremely lean. There's an initial check you can do yourself on the idle air control. It regulates the air from the airbox into the motor and you can get at it in the airbox. Remove the fuel tank and airbox and you should see a little plastic housing that pokes into the airbox with a little white disc that should rise and fall in response to throttle movement. The only problem with this is the FI management light will stay on after, until it has cycled three times.
If that doesn't sort it, you'll need to get a dealer to run a diagnostic check on it to see if it has the correct map and idle fuel trim.

This is for a Tiger but should be close.

It hooks up to the airbox, right side when viewed from the rider's position. the fitting is on the underside of the airbox, right behind the vent hose.

adjust the throttle

let is sit for a day and dry out. you probably got moisture into the spark plugs, or the distributor, or the wires. if you have a battery charger, charge the battery while you are waiting.

JUST A SHOT IN THE DARK ON THIS.

TRY DISCONECTING THE POSITIVE POWER CABLE ON YOUR BATTERY,AND WAIT TEN OR TWENTY MIN.THEN PUT THE POSITTIVE BACK ON IT.

SEE IF THAT WILL RESET IT.

HOPE THIS HELPS
