Need to see what's missing when it won't start... Spark, or fuel. Does the pump run when you try and restart?

The fuel pump does kick in when I try to restart. For the spark, I dont think I have the proper tools to test for that.

Just because you hear the fuel pump it does not mean the injectors are firing. You need a "noid" light.
For the coils, you could pull a coil off and see if the plug fires.

may be a fuel pressure leakdown issue...after the hot soak...try starting it in clear flood mode or put a fuel pressure guage on it and check for pressure leakdown.
