1990 Lexus LS 400 V8 Front Wheel Drive Automatic 224000 miles

All of my warning lights came on the other day. I drove to get a new battery thinking this was the problem. On the way the lights went out. Got new battery didnt fix the problem. So lights come on when started but accelerate above 20 mph then the lights go off. Every thing works on the car but windshield wipers are slow until the lights go off. I am puzzled. Help
