Extended crank on hot start

Hi all,

I have seen posts on this before but I think my situation is slightly different. My truck starts great first thing in the morning. If I drive any where and let it sit from 20 minutes to 3 hours it will do an extended crank and then turn off. If I hit the start button right after that it starts up perfectly. If I let it sit longer than 3 hours it also starts up just fine. One leaky injector was detected so all 6 high pressure injectors were replaced. The 6 port injectors were not replaced but all injectors are working to spec. No signs of over or under fueling. Spark plugs and high pressure fuel pump were also replaced. Low pressure pump was done in 2021. There are no codes and everything is running according to specs. I just picked the truck up from the second shop to take a crack at this. Not even the 3rd party Toyota experts know what to look at next. Just about everything that could be causing this has either been replaced or thoroughly inspected. What else could possibly be causing this to happen on a truck that is performing completely within specs. 133k miles.

Thanks
