As seeing most vehicles are "distributorless" after 1994 or so which would rule that out, are you sure any vapor or unseen moisture aren't getting into vital electronical components and/or harnesses that could be accidently let in moisture that would essentially short it out. Long story stort it could be alot of things, but i would check what i just mentioned. I had problems before with my firebird not starting in heavy rain/fog, it turned out that unseen moisture was getting into my distributor, and a replacement cap was the remedy.

Edit: if it kicks back, then it may that somehow moisture is getting into your ignition system.

Cap, rotor and wires. Do each. Might as well stick a set of plugs in it too.

The G vans ran cap/rotor/wires until after the 02 model year, then they switched to the 4.8/5.3/6.0 engines without distributors. Anyway, thats where I would put my money as well....
