My bluetooth keeps turning on/off continuously

I have my phone paired to my Pioneer head unit and if it disconnects it will occasionally cause the Bluetooth to turn on and off continuously without warning or anyway to stop the cycle. The only way I found to resolve the issue was a factory reset. I just reset my phone yesterday and the same thing happened today when I tried to re-pair to it again after I left my car. As you can imagine, this is extremely annoying, I am hoping someone can provide some insight on a possible fix for this.
