Hard/ slow starting warm/ hot

[RoyBoy]

Been noticing the last few days, truck starts great at 0*F or less, fires off within 2 seconds. Yes I have the FICM "stiction" reflash. When it's hot (running errands in town, etc) it often takes at least 10-15 seconds of starter time to get it to fire, sometimes even 2 tries. It starts kinda "lazy", too, instead of a sharp "BRAAAP" it is a longer, softer "braaaaaaaaaaaap" like it don't quite wannna go. No codes, but will continue to monitor for the next while. Any ideas?

My Truck always seems to start better cold than it does warm. I find that when the truck is warm and you don't let the glowplugs cycle it starts better.
