Had grave doubts it was distributor...

They don't repeatedly go bad. If it doesn't seem likely, it's probably not the cause. But, the wires linking to the distributor's Hall sensor are a classic source of trouble, and they get unplugged and replugged every time you do a swap.
Try wiggling those wires while car is running and see if it dies.
A Hall sensor signal needs to be there for the fuel pump to run.
There is a way to drill out a spare "banjo bolt" at end of fuel rail and tap it for a 1/8" NPT threaded fitting that will let a fuel pressure gauge be installed. That's kind of overkill but might help diagnose things. How old is present pump, and how are the fuel pump relay's contacts?
There's an easy way to jumper things so the fuel pump is on all the time, and having a switch that lets you do that might help diagnose this.
Problems that aren't there all the time are the hardest to solve, as you are finding out.
