78 SB FI difficulty starting when warmed up

[MBTim]

My 78 FI SB convert starts immediately when cold in the morning. After driving and warming up the engine then letting it sit for 10- 15 minutes it will start with much difficulty. Turns over many times before barely starting. It seems to be getting worse. Points/plugs/injectors all in good shape. All vacuum tubes in good shape and fitted properly. Any ideas?

Does it start any better if you hold your foot to the floor when cranking?

Most likely it's flooding itself while sitting, leaky injector(s) or a bad TS2 are the usual suspects, but there's been so many cases of shitty ignition condensers lately I'd start there just because.
