We have ten of these on a cove bar. One of them turns off after about ten/twenty minutes of use only to turn back on some minutes later. It's running in "P" mode (Single channel/address) and there are no FX in the program. It's intensity is controlled by our Phillips Strand console. All the others are good. I've seen LEDs (and regular dimmer packs) come on - AFTER the console was shut down - but never this intermittent behavior. Ideas/thoughts?
