My yucca plant is outside in ground. Was good for 3 yrs and now it's dying! What can I feed it, as the spikes are turning yellow?

Leaves turn yellow for many reasons, so feeding it may not be what helps it.
Yuccas generally are pretty hardy. Their problems tend to come from being overwatered. Has the area been draining well? How much rain or watering has it received? I would check the roots and make sure it does not have a root rot as well. Make sure it is not getting too much water.
Other than that, treat it with a general pesticide and fungicide and that should address any other things it may possibly be.
