55.2-59 Fuel pump

[55Trucker]

Hi all. I have a 55.2 Chevy 3100. I last drove it in 2017, when I found I had to replace the fuel pump to get it going in the spring. The last couple of years it really hasn't been driven, just started a few times. I planned to drive it a lot this summer (now that I am retired!). Lo and behold, it started right up, but I only made it halfway down out road before it acted like it was starved for fuel and died. My wife towed me back, and I found that the fuel pump was not putting out any fuel when I ran the starter. The pump I put in in 2017 is an Airtex 4149. I always have ethanol fuel stabilizer in the tank. Any thoughts on why the pump would give out without much use after 3 years? Thanks!
