Answer
Hi Mark,

Check engine crankcase for evidence of water contamination. Remove spark plug and ground spark plug to engine. Crank over a couple of cycles and allow cylinder to get fresh air. Clean spark plug and reinstall.

Check and clean airbox and air filter.

May be water shorting or flashover due to moisture on wiring and in connectors. When dry, use dielectric grease on all connectors to prevent H2O shorting and corrosion.

Keep me advised on your progress: mshively1@woh.rr.com
