Don't drive in the rain ;-)

Have you checked the Engine Speed Sensor?  It is mounted on the left side of
the engine/bellhousing next to the Crank Position Sensor.  Maybe there is a
crack in the wiring and it is getting wet.  Do you have the engine under
tray installed?  If not, there is more likelihood of water getting sprayed
up in the engine area.

That's all I can think of.  Hope it helps.
