Problem idling (raising the idle with cruise) to run A/C

I have pro star 08 have same problem AC QUIT working by it self when I shutoff engine and restart it's working well like 15 minute and them quit I went 3 different shop and still nothing better any have in idea thanks

 

I have an issue with my new International. I just got a new 2015 from my company and it has the auto start system to re-charge the batteries when they go dead. Problem is it has the Idle Shut Down as well and I was told that the auto start is suppose to override the idle shutdown so it can run long enough to re-charge the batteries. But its not. It will idle for 5 mins then shut down and then I loose power to everything unless I start it. but then I run into the problem of it shutting down again and its a never ending process. The only way I can get a full charge out of the batteries is if I go drive the dang thing for about 3 hours and that's hard to do when I have no time on my clock or im trying to do a reset. Anyone else having this issue?
