It is a fueling issue, I had the exact same problem on my supercharged track car due to inadequate injector size( no CEL or stored code ) . While your injectors are likely not the culprit there is an issue somewhere in the system . Common things being common and the mileage on your car I would replace your fuel filter and check your fuel pressures . If you have a damaged primary 02 sensor there will be a code stored and it wouldn't be intermittent .
My two cents
