caravan died and will not start

I have a 91 Dodge Caravan. We were driving down the highway and I lost all power but it did nto stall, so I pulled over, put it in nutral and reved it up . I put it back in drive and it was fine. I went another 5 kilometers and it did it again, but this time it stalled when I puleed over after I had lost all power, and t hasnt started since. We have changed the modular (brain) tested the fule pump and it has power to it. We took it out and hooked it up to somehting else and it works . I have been loioking all over the internet for wiring diagrams for this back yard mechanic I have, but i cant fid any. I have a feeling that this is somehting simple seeings he has tried all the big things and I need some suggestions on what to try or what it may be. PLEASE HELP ME..

Need more info. What engine? Did you check spark?

Need more info. What engine? Did you check spark?
It is a 2.5 engine and there is no spark.

We found the problem... there is a plastic peice inside the distributer..... it was burnt out.... then we drove it a few blocks and had to have it towed again cuz there was a gas line with a hole in it and it was sucking air... and the fule fliter was clogged.... But the reason it would not start was because of the plastic peice inside the distributer being burnt out.... I knew it would be something simple.
