Sure sounds like a delivery issue. I'd rig a temporary cheap fuel pressure gauge taped to the windshield and go for a drive to confirm you're on the right track. If so, from there you'll have to start looking at the entire system. Check the rubber line connections at all the junctions for kinks, (tank to frame, frame to pump etc..) and even look inside the rubber lines to make sure they aren't deteriorated or collapsed. I've had the rubber lines that looked perfect on the outside, but deteriorated and looked like bubble gum inside, restricting fuel flow. If in doubt, just replace it.
Fuel sock is another area. More difficult to inspect as it requires pulling the tank, so I'd save that one for last after you've exhausted all other possibilities. Could be simple and just the pump getting weak. Not much to the fuel systems on these cars so should be pretty easy to narrow down.
