94 k1500 Blazer dies

I have a full size Blazer with a 350 in it. For the last month it will just die while driving. There seems to be no pattern. After it dies it will turn over, but not start for at least 24 hours. Then it seems fine and will run great for at least a week. I have checked and I am getting fuel to the trottle body and have replaced the ignition coil. Any thoughs?

Check fuel pressure.

Done a tuneup?

Check engine light on?

I am not getting a check engine light. I did a tune up about 6 months ago, cap, rotor, plugs, wires. What would cause the fuel pressure to drop? The fuel pump is a litle over a year old and I just changed the fuel filter.

When it does and won't start, check if there is spark out of the plug wires.

check the computer ground wire at the top radiator hose inlet neck on intake manifold. It should be a thin beige wire.
