Default 2007 Silverado air bag light

Hello, I went to turn my 2007 Silverado on today. It turned one for about 10 seconds and then shut off with a service air bag message on the cluster. I turned the key off and tried again and same thing. On the third try it fired up and ran. It has done this in the past but hasn't in a while. What could be causing this? Thank you.

Sounds like something is going on with the data communication line as in one of the on-board computers in your truck is wigging out causing the rest of the computers to shut down. You need to get your hands on a scanner that can read body control trouble codes and go from there.

No a vacuum leak wouldn't cause this issue.
