intermittent radio loss

[corpsedoctor]

LG Optimus Black. Doesn't matter if rooted or not or which ROM. My cell radio will suddenly stop when streaming. Doesn't matter if using 3G or WiFi. When I try to restart the app I get a 'no signal' error. Only way to solve is to reboot. Ideas? Thanks. (Running gROM 2.2, ZVH, and most often happens with TuneIn Radio app.)
