I have a 1993 Toyota Tercel (only 92,000miles on her)
She is a great car when driving around town and back and forth to work, never really any problems. took her on the highway where the speed limit is 70 and when i got her up to 70 her power decreased after a few minutes, and then she died, I got her back up running, but am really clueless about cars, anyone have any ideas???? Please Help!!!!

OK. first off.......... Please don't post duplicate questions
As for your problem, 2 things need to be checked and this needs to be done while the problem is present
Check you fuel pressure and rig the gauge so you can monitor it while driving to observe if the pressure drops when the problem occurs.
The other thing to look at if the fuel pressure checks out is a plugged up Catalytic Converter. The easiest way to check this is by disconnection the front exhaust pipe from the manifold. You can also pressure check it through the O/2 sensor hole if you have the equipment for that. It should not exceed 2 or 3 PSI there.
