My race car is doing the same - intermittent poor power/stalls at idle. Then it runs fine. Then it runs poorly and stalls. Feels like fuel starvation. Replaced fuel filter, fuel pump, and MAF. Ran two tanks of gas from different stations. No CEL's. Considering crankshaft position sensor next but also looking at fuel tank vent/recirc system.
