problem with my 2006 tundra 4.7l

Starts well in cold weather, but when it has been running, then shut if off for 1 to 2 hours, the engine rolls over a extra 3 to 5 more times before it actually fires up.
Fuel tank was cleaned and new fuel pump because pressure was low
and at end of 2019 changed all injectors because dealer said that should be it.
They installed them and it seemed to be working, but now the weather is getting warmer its starting to do it again.
Dealer thinks its the parts I got, but they are OEM genuine new parts, just I didn't order from them. I think there is a underlying problem.
Hope someone can help

 

How many miles?

 

Sure sounds like leaky injector(s).
