Yet another stumbling C4
My '87 vette dies while I was driving it Sunday, acted like it was out of gas. I was able to get it started again and decided to head back home since I was pretty far out. It died repeatedly, at least 8 or 9 times on the way back, was able to restart each time. The last time I thought she was done, stalled 1/4 mile from my house and would not restart. After about 10 minutes I got her going again and limped home.
I've googled a bunch and come up with many different possibilities, but this is where it gets weird. When I first got the car 2 years ago I let it run below 1/2 tank. It acted the way it did Sunday, limped it 4 miles to my house after repeated restarts. When I got home I thought maybe the gas gauge was bad and put some gas in that I had in a can. Started right up and ran fine. Until now I would start noticing her stumbling when it got close to 1/2 tank so I would just fill up and all was well. Until now. Sunday I had almost a full tank of gas, I know the gauge wasn't lying because I just filled up the day before.
I'm stumped, and hope that the symptoms might give a clue as to what's going on. I'm leaning toward the fuel pump but I understand there are multiple things involved that could affect this. Any ideas? And thanks in advance!

Signs of a fuel pump sock filter possibly has disintegratde and allowing debri to get past and hinder flow at the right moment or just clogged.If no maintenance records I would at least replace the pump and the filter AFTER running the tank empty with a gauge on it just to see what's going on.

Pull the fuel pumps, easy 10 minute job and check the hose connections. I had similar symptoms and found one of the hoses on the fuel pump just hanging there, the clamp had come off. New stainless steel clamp and back in business. A good free check with minimum effort before replacing parts.

Thank you I'll try that!
