General Maintenance & Repairs - The TA wont start!

So, I was parked and listening to some music and all of a sudden I lost all power.
I thought it was just my battery, had my friend jump me and it fired up. It idoled extremely high though and shut off again.
Jumped it some more, got it started again and it idoled fine for about a minute.......then shut off again, all on its own.
I'm guessing its the alternator?????
Any advice???? Its parked about 2 hours away, sitting in a parking lot.......sucks!
Thanks guys!

What does the voltage look like while it's running for that one minute?

Well it must be the battery has went dead, seeing as you have the electric fuel pump so if the bat is dead then you cant get fuel which may be why your car is shutting off. High idle can be caused by a vacuum leak. I say get a new battery then go from there, but i think a new bat. will fix your problems :D
