318 is suddenly doing THIS:

I am running a stock 318 with a Holley 2280, stock ignition and 4-wire ECU, single ballast.

Out of nowhere, it's started falling out at part throttle.Doesn't matter if it's free running or under load, above 1500 rpms it'll begin cutting out and die if I hold my foot in it.Also starts smelling like an arc-welder at that point, weird combustion odor.

Restarts with about 3 seconds of cranking, and I can rev it through the "falling out" spot, so it's not a complete loss of spark/fuel.

I replaced the ECU just to eliminate that, since the old one had overheated in the past and also replaced the negative cable.No change.

Where should I start looking?
