1997 Porsche Boxster died while driving.

[xX2pro4uXx20]

I was driving the car and it was fine until I came up to a stop light and once the RPM'S dropped, the car died in neutral. I went to start the car but it wouldn't start. I did get it to start whenever I pressed the gas and tried to start it and it didn't die as long as I kept the RPM'S up. The temp gauge had been flashing for a couple days so I checked the coolant and it was indeed very low so I figured it had overheated and it couldn't start because it was heat soaked. The temperature was past the 0 in 180. I made it back home and I waited about and hour and I went back out and it still won't start. I did find a leaked coming from a tube that isn't connected to anything. And doesn't look like it could be connected to anything. My car is a 1997 Porsche Boxster with a manual. If you have any questions that could help you diagnose the problem then let me know. I also did an one 2 test and It came back with p0117 I believe it was. The one that indicated something wrong with the coolant temperature sensor.
