'93 300ce

My 1995 E320 with 86k miles, that has me concern and puzzled. In the last 12 months I’ve experienced a Hot start issue with longer than normal cranking and poor idle for just under 1 min. This has happened 3 times, it seems to occur on sunny 75f plus days after driving for 60 miles or so and then the car is parked for 5 hours. The coolant temp is at atmosphere temp. I haven’t experienced this if I dive for an hour park for 30 min, the car starts just fine

I have updated upper and lower wire harness, new battery the holds a good charge 12.4v, a strong starter. No check engine light and no codes on blink reader.

Where to start, any ideas?

i would get a blink tester and start testing
