I have a Hoss tree planted next to a Fuerte. Both were planted at the same time. The Hoss produces every year. The Fuerte has not for the last couple of years. It will blossom but not produce. Could there be a problem being planted next to each other.

No, there is no problem with them being planted near each other. It could be that there is not enough potassium and phosphorus in the soil for it to bear. Alternatively it may have not reached maturity enough to bear fruit consistently.
