Can FP be fed out of (2) separate diesel generators via fire pump transfer switch/controller? The first generator also serve building egress emergency panel. The second generator is dedicated to fire pump. Thought NEC requires FP to be fed out of a reliable power source?

The generator has to be capable of starting and running the fire pump along with any other loads on it. It does not have to supply locked rotor amperage like the utility. If the generator supplies optional loads, those may be shed by automatic means before pump starts.
Do you know exact code section about this arrangement?

I am not sure there is a code section that permits two generators without an utility supply.

This is a discussion to be had with the local AHJ, but it looks like you need a source from 695.3(A) in order to use a generator as outlined in 695.3(B)(2). Two generators don't appear to cut it.
