Battery good. Lights good etc.

Any ideas?

You can have lights working and still not have enough battery to start. Try jump starting it. You should hear the starter solenoid click. If nothing, probably the starter! If the battery is bad, make sure you check your alternator to ensure it is keeping the battery charged.

If it's only when it rains, I would suspect a poor connection or high resistance in the circuit.

I agree.  Look for loose, corroded, or burned connections, especially any that could be susceptible to moisture intrusion.  Check the cowl and windshield frame for leaks.

Do you hear the solenoid engage or at least click?
