Sounds like the immobiliser could be playing up 1st thing I did was get rid of the 16 year old alarm off my recent purchase, as had one on my 1st fazer a few years ago went tits up & was lucky it was a simple job to remove I remember happily bashing my large hammer onto it in joy ?
Some are wired directly into loom & same color wires easier to change that than faf about too much lol
