Model A quit while driving -- won't start

[Eskildsm]

So took model A out for drive -- started down my lane and going downhill and car lurches then dies. I have plenty fuel that's not issue. I put new condenser in-- no help-- I find the fuse blown ( yes should check that first) I put new fuse in and turn it over still won't start- look and fuse is blown -- get another one it blows while I'm trying to put it in. So disconnect battery and put fuse in then hook battery back up and before I can get to fuse its fried. So I bypass the fuse and have hot where battery hooks to starter but no where else. Earlier I had also put new amp meter in and no help!!! Any ideas???
