Based on what you have said so far here is what I think... 
First: Taking your Chondro on an unnecessary road trip was not wise, but I doubt it caused the death of your Chondro. I say this for 2 reasons... You said and ate when you got home, and if it was stressed it would not have ate.. Second, people bring Chondro's half way across the US on a regular basis for shows and if it was going to kill them they wouldn’t do it...
So lets eliminate that option...
Second: I am going to guess that you did not get your snake from an actual breeder. You probably got it off of Kingsnake and it was probably from a broker... Meaning it was a wild caught or farm bred animal. It is common for an import of any kind to pick up parasites, either from the initial location or in route or even from the broker. For this reason most breeders or experienced Chondro keepers only buy from other breeders.
The one thing you have to bear in mind is that Chondro's are not your average snake that is sold all over the net... The majority of other pythons and boas are captive bred where as the vast majority of Chondro's are imported from a farm in Indonesia... So what I am trying to get at is your Chondro probably died from parasites... Most parasites can be treated, if you know what you are doing, but I would highly recommend keeping it simple and buying a CB next time around...
You mentioned that you want another... I would strongly suggest you contact a breeder, like Rico Walder and talk to him about buying a nice CB baby or just go to his website and browse for yourself, you can google him...
I am sorry about your loss… I hope to see you on here in the future showing off your new purchase…
