[QUOTE="ytradio, post: 435939, member: 19779"] Stored energy in the capacitance of the entire circuit of the radio is bleeding down until it gets low enough that the radio won’t play anymore. If it is switched off on the radio itself it should not do this, but if the vehicle is shut off and the power is no longer flowing it can do what your describing. I believe that the main reason you see this happening lately, is because newer electronics draw less power to work than older stuff did. Even solid state older stuff drew more power. My LED TV will play a few seconds after a power failure during a storm, but go off immediately if switched off. If you take a look inside your radio, you will probably see micro surface mount components so small that they cannot be assembled in the conventional way. They can work with very low amperage draw.
