DYS 4000 Starting Problem

DYS 4000 24hp - 42" cut. Wires were cut to ignition switch. Had someone wire them back. He only had a little electric tape but it worked. Now I was mowing, went in a hole on the left side, but the mower pulled right out then it just cut off. No sputter, Nothing, Just went dead. Well the engine turns over with no problem-it is getting gas-there is fire at the spark plugs-but the other change is now the engine will turn over when I don't sit on the seat. I thought the seat kill switch, because it was working properly, but I shorted over the switch (or hope I did) and still no starting. Any ideas?
