It makes sense in a way. Most alternators reach max output somewhere above 2K rpm so if your main battery is shot, it might take that many rpm to feed enough current demands to make the engine run normally.
An electrical load test might help and imagine a DIY oriented auto parts store has a free tester.
If you do go with a fuel system repair, definitely do it outdoors and not in the garage.
Good luck.

Good thoughts. Brought the battery to AutoZone to get tested. Read as having a low charge and they charged and tested it. It "tested bad" as in it probably wouldn't hold a full charge. It was 5 years old in a car that doesn't get driven much so I got a new one.
New battery installed, took like 10 seconds to start the car which I found a little odd. It cranked fine. High idle on startup was fine, but when it warmed up a bit and lowered the idle the same issue started happening.
I'm thinking taking a while to start might further indicate fuel flow problems? Alternatively, the alternator could have an issue resulting in a similar situation to a bad battery causing low fuel pressure...
