Intermittant AC
 

My AC is acting weird. After driving 11 hours straight on a trip, my AC stopped blowing cold air. I changed the setting from outside to inside air, and lower and raised the temp but nothing, just warm air. I stopped overnight and guess what the AC worked in town but then stopped. I decided to drive back overnight instead of the day and after about 10 hours the AC only blew warm air. Next morning I took the car over to the Honda dealers to see what they could find, by the way, the AC worked fine while driving over to the dealer. The dealer said everything was operating normally and pressure were OK. Has anyone had something like this go on before? I have a 2006 Odyssey Touring model.
