Sounds electrical to me! Best thing to do is find a warm dry day when it will start just fine once it does mist the electrical components with water. Go around the spark plugs. Plug wires and keep misting. When the vehicle hesitates you have found the problem part.

Or you can pop hood on a night and run it in the dark no lights or anything and look for spark that is escaping.

Had similar situation with my 1994.

Pull the doghouse (interior engine cover between front seats) and replace distributor cap and rotor [I was told my 1994 did not have a cap and rotor!]).

Done (a little time, a few [very few] dollars, and you are back on the road again).

Shalom.
