When you say it won't start when it's hot do you mean engine is cranking over but it just does not fire up and run Or is the starter not engaging the engine and turning it over? Do you have a code reader to see if there any malfunction codes set in the computer?

Lean codes are P0 171 series. There are multiple things that can cause the engine to run lean up to and including too much ethanol in the fuel. You will get vapor lock in the fuel rail and it won't start hot. How many miles are on the vehicle? Do you have a scan tool?
