1990 940, starts, runs, sputters, dies. Will start, repeat sequence.

My B230 Regina has been sitting for a few months, ran sweetly before. Now it starts readily, idles, will go in gear for varying amounts of time, 30 seconds, to half a mile down the road, then it starts to sputter, cough, bogs badly on pressing gas, then dies. She starts right up immediately, idles and maybe gets me back home barely before quitting again. I've checked in-tank pump, sock is fine, I removed the pulse regulator thing above the pump(some other thread said it might be leaking air), no change. Put a few gallons of fresh gas in, thought it might be spoiled gas, no change. Put new fuel filter on, no change. Fuel lines all look fine. Changed out the radio suppression relay, no change. Any ideas?
