1973 280sel 4.5 dying when warm

So, Mo is dying when she warms up. She starts fien cold, runs until reaching operating temp and then, she dies (and giving gas with the accel does nothing).

I thought a fuel pump, but why then does she warm up just fine? She has been sitting for 3 months in the garage (while it's been cold here) and she was filled with 93 octane back in January when she seemed to run fine when she was all warmed up.

Any ideas?
