1993 Dodge Caravan engine wont start after died on highway.

For a while now my caravan would cut out while driving at higher speeds(40-70mph). It would just stall for a moment or two and then pick up again. Yesterday, while driving down the Interstate at around 75mph the engine completely died. I coasted to a stop on the shoulder and had it towed to my house. Since then I have replaced the plugs and wires, d-cap and rotor. They were all in bad shape, no oil on plugs though, just white carbon. I am beginning to think maybe this is a fuel pump problem? It cranks when I try and start it, just never sounds like there is a spark. Any suggestions on what to check next would be helpful.
