Help 2007 Silverado
 

Today I remote started my 2007 Silverado classic and as I walked up to it, it stalled. When I turn the key it attempts to start then dies and all my gauges drop to nothing, like there loosing power. I also noticed that my remote wont lock or unlock the doors. The lights just flash twice. But I can lock them with the electric lock button. Any thoughts anyone? Also I can hear a loud click coming from the top of the engine just under the plastic cover in the front when I turn the key to the on position and the off position. And if I try to remote start it the alarm goes off.
