I'll go with a possible fuel issue, newer pump getting weak, or filter plugged. The fact it runs well when lower fuel flow is required, and falters under higher fuel flow indicates a weak pump or filter restriction. Almost like vapor lock. When it won’t start will the fuel pump run? Some of the replacement pump quality is rather dubious. If the fuel filter hasn't been changed, it should be one way or the other. On the long shot it maybe an electrical issue, seems there have been ignition switches causing problems. Squirting the crank position with freeze spray may be worth a shot.
