2016 SR. When I start my vehicle, my stereo works for about ten seconds and then all sound stops. Doesn't matter if it's aux, radio, CD, whatever- no sound. Like someone clipped the speaker wires. Sonar also makes no sound even though the indicators light up. Stereo will sometimes come back on intermittently. No staticky like a bad connection, 100% on or 100% off. Any ideas as to what is going on?

 

I would use a code reader. But sounds like a short or fuse.
