Try this when you go to start it hot - turn the key from off to run (not start) 4 - 5 times. That will cycle the fuel pump and "fill" the injectors if they have leaked. If it starts right up, you're losing fuel pressure - likely through the rebuilt injectors.

On a hot day, my Cherokee will heat soak and boil the fuel in the injectors. My solution is to hold the pedal 3/4 of the way down and race it at 3000RPM for 20 seconds, then it's fine. The mechanical fan really makes a lot of noise at that rpm!
