I just pumped that from the station the

come out clear/clean looking then turn
foggy 10 min later? bad gas? water in it??
The smell is from what I can tell, smells like gas

Could be a red herring. After sitting open for 10 minutes in high humidity,
your gas might be absorbing enough moisture from the air to cloud up. Maybe
try collecting a sample in a closed container and see if it still goes
cloudy. Ask the cat you bought it from if anybody else has complained or try
some of the suspected bad gas in your lawn mower or something. Diesel fuel
has a pretty distinctive smell and would probably have a more profound
effect on your engine than you described.
