Holley 750 Question

OK, so I have a Holley 750 on my 383 daily driver...

It has Electric choke & Vacuum Secondaries.

It's been running just fine since I installed the Holley a little over a year ago..But for some reason it was running kinda funky the past couple of days (Engine stopping for no reason, seemingly as if Out-Of-Fuel *it was not*, so I Throw it in NEUTRAL while coasting, re-start the engine and go off on my merry way, till it did it again a few hours later.. )

Anyhow, I got it home, popped the air cleaner and noticed that the Vacumm secondaries (butterflies) do not come ON when revving the engine to/at WOT...

Ya guys think it may be the Vacuum diaphragm gone Kaput..?

Fuel filter obstruction..?

Or could it be a Distributor / Electrical issue..?



It has done this about 6 - 8 times in the past 3 days


What bugs me is that after it dies, it starts again after a few seconds (2 - 3 seconds) of re-start..


Thanx for your time..
