Where you getting any error lights when it first shut off?
You can try to do the reflash of the software -- if you don't have the VLink, you can send the unit to us and we would do it for free to see if it helps. Its hard to say 100% either way from the description. Would also try to recalibrate with the radio - its possible that it is not getting the signal, if you only get the red power light after you turn it on.
Please feel free to PM me or email me at
