Sudden change to aggressive behavior question

We have three dogs. A 6 y/o female purebred German shepherd, a 4 y/o female black lab mix rescue and a 3 y/o male golden retriever, Australian cattle dog mix rescue - all fixed. We’ve had them all together for 3 years and never had a problem. Over the last week our 3 y/o male has become aggressive towards our 4 y/o female. First it was over a toy, then over food. I’m stumped as to what could cause such a sudden change after 3 years of harmony. Any advice?
