2007 jeep wrangler

2007stalls while driving at 65 had it to the dealer 4 times they have no idea what he problem is please help

I am assuming it is under warranty.  If use the following references. Don't give up going to the dealer and consider calling the Jeep people directly bypassing the dealer. 

Document every visit to the dealer.
