2000 neon dies while driving

What is your question?

My 2000 Plymouth Neon stopped responding tonight while I was driving down a hill. I Gave it gas, it bogged and the speedometer failed. The Tach that I had running off the coil pack failed as well. When I pushed in the clutch to stop the drive-line the car died instantly. It would come back on if I "bump" started it, but ultimately died when I stopped. There is no spark coming from the coil pack on any prong. All other electrical in the car works as far as i can tell, i do not have a power prod on hand. I could only think that the coil pack has gone out but if the coil pack has gone out why would the speedometer stop working? Also is possibility of the alternator going out, in which case wouldn't the car have drained the battery before dieing? Any suggestions?
