Code stops after some time using delay

The a0 is connected to a potentiometer, you turn it to get the different modes. After it stalls out, you can switch modes, leds are hooked up to each to show what case it’s on. It just doesn’t move any servos after it stalls out.

Do not power the servos from the Arduino. Set up a separate power supply. I have seen where an sg90 can draw 550 ma.
