Stereo problems

We just got a used 2011 Toyota Tacoma when playing music if the volume is just a little elevated in the 30s or 40s music willl play for a while then completely shut off we did the volume control turned it on high and then turned it off but we’re still having the same issue both whether playing music through the phone or just the radio any ideas what Might be causing this? Thanks

 

Does the whole radio power off or just the audio output??

Is the time it takes to shut off always about the same or is it random ??

Driving or when parked the same ?

Sounds like a poor connection . as things warm up an open circuit occurs when things cool down it works again

Since you just bought this hard to know if it is temperature related

30s and 40s I am guessing is temperature ?
