Windstar Cargo Van 2000 Ford Windstar Stalled Out?

2000 ford windstar stalled out? - windstar cargo van

I have a 2000 Ford Windstar Cargo Van, and I drove one day, and only the outside positions. That's happened before, and no signs to warn me of this problem. I have an idea which could be the coil, but I'm not sure. Whenever I try to start it, not him, and they make sparks. Can someone tell me how much it would cost to replace the coil if it is.
