Tucson,AZ 106 degrees today!

I have a Trane 13i heat pump that will not run during the day when it is hot outside.

Blower comes on, but the condenser unit just short cycles and will not run. The condenser and fan click on for 1-4 seconds then click off.

After the sun goes down, everything works good. It runs continuously and cools great.

Any ideas?????
