2011 camry 4 cyl stalls when hot
 

have a 2011 camry 4cyl LE with 30K miles. twice in the past year it has simply stalled when driving up hill on a hot day with air conditioning on at altitudes of 7K feet. After about 20 minutes, it starts and off we go. If it were carburated I would say vapor lock. any ideas?

yes, there is no other reason but vapor lock.
