My ST2 had a similar problem; presumed the battery had died as the charging system was showing 14+V but it then died again a couple of days later so replaced the voltage regulator and the problem never returned.

My conclusion was that the regulator was OK when cold but stopped charging when hot!

Thanks chaps, have already changed the fuel filter so rules that out I guess. Ive been very suspicious of the regulator as I have had varying readings off the battery when its running so I have been thinking of changing it. However, looked into this and there are several different types and I got very confused with the options but I need to look into this again.

Cheers.
