I had the same exact probelm. I drove for 20 miles the car stalled out and would not start. I had it towed back to the house. I jumped it. Drove for about 2 minutes and stalled again. And then i bought a new battery, plugs and wires. Still wont start up. And when it does it doesnt stay running for long. However, if i spray starting fluid in the air intake it will start up and run.
You could have a clogged fuel filter you didnt say if you have replaced it ;the fuel pickup in the tank could also be getting clogged when engine is off the trash in the tank settles down then when it cranks it runs for a few minutes until the trash clogs it up again
I have a 1993 chevy 1500 4x4,with a 4.3 engine,and tbi,i have no fuel pressure,i have changed the fuel pump,fuel stainer,fuel filter,fuel pump relay,and fuel pump fuse,but i have still have no fuel to the filter.
Hi, sounds like your fuel pump is going out, not giving enough fuel pressure.
Hi, look on the fuel rail under the hood going to the engine for a valve that has a plastic screw type cap on it, like a car tire valve cap. Connect a fuel-pressure tool this valve to check your fuel pressure. If the fuel pump is bad, this test will help.
Hi, well to keep it simple, you narrowed the problem to a fuel related problem. Since there are many components to the fuel system, fuel regulators, fuel sensors, pressure regulators, computer, wires (one frayed wire will do what your describing too, and I can't see the car, it is best to take the car to a mechanic or someone who has a fuel pressure gauge tool. From my experience, fuel pumps either work or they don't meaning it is very rare for a pump to start "dying", it will either turn on or never turn on again.

Thanks a lot for the quick response. I have not replaced the fuel filter or the pump. The filter looks like it is fairly new i did take a look at today. And when i turn the key on i can hear the pump going. However it could be clogged like you said. I also hear that there is somesort of a "spidergear" inside or under the intake that has something to do with the fuel distribution. IF you have any other solutions or ways for my to dignose the problems or how to eliminate certain things that are not the probelm. Thanks alot to everyone helping me out.
I actually was told to turn on and off the car about 15 times and listen to the fuel pump. It was making a buzz sounding like it was working. It stayed constant. Then i addes 2 more gallons of gas and tried the on off meathod again and the fuel pump was not making the buzzing noise... i got nothing.
Im assuming that the fuel pump was trying to work and either dying or not working properly. Does this sound right.
I would test the pressure however i do not have the tool required to do that job.
