Post poor running suburban

Help. coming home from delivering Jeff's suburban to Desert Rat, my buddy's suburban started to cut out, surge, buck and run really bad. Slowed us down to 40 on the freeway once. Then it would clear up and we could run fine for a couple miles before it started back in again. He changed the fuel filter yesterday and filled up with gas, but still the same. Any ideas? fuel pump?

sounds to me like the fuel pump is about to go to fuel pump heaven.

I had a 86 that would buck and carry on sometimes but only at certain speeds. Turned out it had a crack in the distributor cap. Worth checking anyways
