iv not long owned this original vl turbo. mods are front mount, pod filter, boost controller etc. starts and idles fine. after warm up revs fine. but if i drive it after about 5 mins it will shut down and not start untill it cools down. if i pour water on the dizzy it will start again..

You need new crank angle sensor mate 10 min job

I had this Prob found out it was the plug on the front of the dizzy try that

either of the above... more than likely crank angle sensor. easy quick fix.
