2000 Saturn Won't Go!

my acceleration went out on me this morning while i was on the freeway.
When I went to step on the gas pedal, nothing happened. I let it sit for
about 15 minutes, while it was running, and then I tried it again and it
went for about 50 yards, and wouldn't go any more... It started to die
when I tried it again. Then I waited another 15 minutes and it ran about
another 50 yards and the acceleration went out again. I got it to the
nearest gas station and left it there. Can someone tell me what the
problem could be? And how to fix it? I looked for a manual and they don't
make one. thank you thank you
