Car hesitates, dies

I have a 1987 Trans Am, 305, 5.0L, carb with quadrajet. I have a problem with fuel pick up, i think. I have replaced the electric in tank pump (once around beginning of this year), and the mechanical pump (4 replaced in the last year), they are both brand new pumps. today I was driving down the road, not getting on it, just driving, and the car sputtered and died. I have had issues with it hesitating in the past, and had to replace all fuel pumps to fix the problem. It still has occasional hesitations, but for it just to up and die on me just pisses me off, even after I have dropped all this $$$ into it. the car has 55,000 original miles on it. it sat most of its life, so I put brand new hoses, radiator, heater core, thermostat, etc for cooling system. the fuel system is ALL brand new, down to hoses, filters, pumps, rebuilt carb, etc. it seems like this car hates me, or is it backwords??? can some one please point me into the right direction on what to do next???

Just realized this was buried in a sticky (where it didn't really belong).

Have you gotten anywhere with the problem?

I'm guessing doing the fuel stuff didn't "fix" the problem, because you aren't having a fuel problem. If you verified it wasn't getting fuel, I'll take that back.

It isn't unusual for these cars to have ignition components die. Typical culprits are the ignition module in the distributor, pickup coil in the distributor, and coil. Any or all of these could be bad on your car. A worn or bad distributor cap or rotor, bad coil wire, loose coil connection - all have cause the symptoms you're describing.

So, if it is still happening, do your best to determine if you still have spark when this happens. Easiest done with two people, but if you apply some ingenuity, it can be done single-handed.
