Engine is 4.9L V8. Wires, plugs and distributer cap replaced about
3000 miles ago. Car was running fine up until that point, however I
had just refueled 30 miles previous after letting fuel run too low
(gauge is tempermental). Thought I may have picked up a vapor lock
along the way. I will pull the plugs tonight though and look for any
tell tale signs.

I'll give it a shot thanks. I do get a large amount of gas vapors
coming out of the carb tho when the air cleaner is off. Would faulty
spark plugs cause a flooding condition because it will run for about
ten seconds and then quit. It will start again if I let it sit for an
hour or so, but the same symptoms appear.

Thanks

I think spark. The fuel is there for sure.

Even if something like the float stuck, it wouldn't matter above 50 mph.

Was it raining? Maybe a splash of water got the distributor cap and
cracked it.

You can do a base check for the timing chain having jumped by putting it
on the timing mark on the crank and seeing if the rotor is pointing real
close to # 1 under the distributor cap. It should be 'just' after
center on the pin.
