this one's a shot in the dark but it happened to me.after spending many manhours and many dollars,the hot stall/no start till cool problem was the 12v power lead to the fuel pump had fallen on the exaust causing the insulation to melt and short it out.when it cooled,the connectiion was broken and the car ran fine.
