09 MDX Elongated Crank - Start

Hi All! I have a 2009 Acura MDX that has a long crank start issue. Cold starts the vehicle starts right up no issues at all. If I drive it and let it sit for 15-90 minutes and try to start it after, it cranks for a long time and finally starts. It’s never not started. I’ve replaced plugs, fuel pump, EGR valve canister vent and still having issues. Let me know what ideas you have. Next will be injectors.

Have you cleaned the throttle body and the MAF sensor, the engine air filter okay? Long term and short term fuel trim okay?
