What's wrong with my GMC Sonoma?

It's a year 2000 with the 4.3 V6.

It starts and idles fine, and if you're light on the throttle it seams to run fine.

But you can't open the throttle beyond like 30%, or else the power cuts out and the rpms die down until you let up off the gas pedal.

The check engine light in the dash is on.
