Hello!

This is a classic symptom of fuel pressure loss.

When a fuel injected engine is shut down, it must retain fuel under pressure in the fuel lines and fuel rail so that there will be fuel available when the engine is restarted the next time. If the fuel pressure is slowly bleeding down over a few hours, it will result in exactly what you are describing.

Fuel pressure can bleed off through a leak anywhere in the system, a faulty fuel pressure regulator, or (most likely) back into the tank through a worn fuel pump.

To diagnose this problem, what is necessary is to take the vehicle in to whatever repair shop you normally use, and descrie the symptoms to them. They will want to keep the car overnight, and will attach a fuel presure gauge to the fuel rail before going home for the day. The next morning, they can tehn take a pressure reading when they come back in to see if fuel pressure has bled down overnight.

I hope this is helpful; if so, please click my accept button! thanks!

it could be a faulty new fuel pump, a tiny leak anywhere in the system, a dripping fuel injector, or a faulty fuel pressure regulator.

I would definitely not replace any parts without first having the test I described in the answer above performed to confirm that a fuel pressure loss is indeed occurring. With such a slow pressure loss it is critical to take an overnight fuel pressure reading, both to confirm the cause of the starting problem before any repair attempt is made, and again afterward to confirm the repair.
