My ST4 had a very similar problem! I know you say you've "cleaned all the wiring connections", but did you check/clean the big main wiring harness multiway connector at the left front of the fairing? It's prone to water ingress & retention, resulting in significant corrosion of the male/female terminals. It's easily accessed by removing the small dash left side-panel and 'hinging-off' the top half of the connector, but replacement would means fitting a complete wiring harness! I cleaned mine with a small, stiff, non-metallic brush & WD40, rinsed off with brake-cleaner solvent & let it dry, then slapped on lots of ordinary grease before re-assembly. I've had no problems with it since despite riding in the wet many times over the winter.
