- Temperature sensor (wrong signal will cause ECM to add too much fuel when engine is warm, causing long cranking time before engine will start)
- EVAP Purge Valve (when they stick open, they allow gasoline fumes to enter the intake manifold, causing a rich condition and long cranking time before
the engine will start)
- Possible fuel pressure problem (when shut off, loses pressure which results in vapor lock and long cranking on a warm hot engine).
Check if any fault codes are stored in the ECM. That might help the diagnosis.

No fixing at this point. You need to check those items, no need to waist money on parts that you might not need.
Once I have the exact engine code, I can supply specific info so you can check those components.
The more often it happens, the easier it will be to find the problem.
