The two events are unrelated. 
No bus means the cluster isn't communicating with the PCM. If the truck won't start... it's likely one of the sensors on the 5 volt bus has gone belly up, and taken the whole thing down. May also be a failed PCM. If you have a scanner, plug it in, see if it will talk to the PCM.
Welcome to DF! Moving this to second gen ram section for ya.
