Potential fuel pressure issue

I've got the stock 305 TPI in my car. Around June of last year, I noticed my car acting weird - especially on hills. When I start to give the car more throttle (to climb a hill or accelerate quicker), sometimes the engine drops a few hundred RPMs. The more gas I give it, the lower the RPMs drop. Sometimes, letting off the gas and getting back on the gas fixes the issue. Other times, the engine will correct itself and raise about 500-600 RPMs in a matter of seconds without me changing the amount of throttle I'm giving the engine.

On even more rare occasions, the car will jump between about 1800 and 2000 RPM's while climbing hills every second. Giving more throttle bogs the engine down more, so usually I just keep the throttle constant while I make my way up the hill bouncing between those two RPMs. Once I reach the top of the hill, the car usually corrects itself and raises about 500-600 RPMs to where the engine should be running at.

So after almost a year of this, I'd like to fix this. It's a sporadic issue that doesn't happen every time time I climb a hill or give the car a lot of throttle, but it happens often enough that it's getting annoying. And every time it happens I wonder if the car will die while I'm climbing a hill or merging onto the freeway. I'm thinking it's a fuel pressure issue (fuel pressure regulator maybe), but I thought I'd come and ask about it on here before I start tearing into my car.
