My blazer recently stopped running it would start

My blazer recently stopped running it would start then die, I d restart it the have to immediate put it into gear or rev the engine to keep it running but once it was running is was just fine. Them now as i was driving it just stopped. It would start then drive a few feet then stop. I still have power and the starter is new. I bought some engine starter and that worked long enough to get me home. Is this signs of my fuel pump going out.
