Won't Idle In Neutral

Never had this problem. Put the bike in neutral, start the bike to idle, 10 seconds later it dies. Repeat...A bit later I start the bike and immediately put into first gear. The bike continues to run. Drive the bike stop put the bike in neutral. Within 10 seconds it dies.
Ideas?

Just google Triumph Thunderbird Storm map sensor mate, you should find plenty of pics and explanations of what to look for

I have read some articles about the vacuum lines under the tank being flimsy and causing idle problems. I will be looking into that shortly.
