Car dies at full throttle!! Help!!!!

Car drives fine but when I go to full throttle check engine light comes on and motor dies. When I let out of the throttle a little, car stats to run again! Help. Could it be a bad TPS sensor?

Thanks!

Dying with throttle could mean you're running far too lean. Check for vacuum leaks. Also, what's the condition of your fuel filter?
