I neglected to mention it but, yes. I did check the plugs, as you suggested, and are dry and clean. The rotor button and all components on distributer are new, but checked again last week to be sure. it is a okay.
I rely on your suggestions and do follow them exactly, THANKS.

Thanks, scope103,

I do not possess a gage for the fuel pressure, simply loosened the supply rach bolt and gas squirted out, which I until I am able to accurately do it, I have to rely on this method.

Maybe you didn't realize it but in your first reply today you said you would stated " I will not follow the advice of Sphealy, and check for plug injectors".
Is that because when you checked the plugs they were dry and you feel that has eliminated the possibility of the clogged injector? If so I would agree with you. It just didn't sound that way from your first post. Then in your second post you stated "I rely on your suggestions and do follow them exactly, THANKS" The two post make it difficult to know what has actually happened.

Most everyone I have dealt with on this forum generally is very willing to help but you have to provide all information of what has been checked/has not been checked and how it was checked to give the others the most information to help you. If you simply say I won't take advise from someone without explanation it leaves far more questions than answers. The quality of information you provide the group will directly reflect the quality of answer/suggestions you receive back.

Once again I am not offended if you do not wish to ponder my suggestions. I only wish to help you better communicate with those trying to help you.

The above link is the same I posed earlier. There were lots of good options to check in this thread if you start from the top and read through them.

Sorry

My apologies, Sphealy, I don't know how i could have written "I will not follow..." What I meant was the opposite, which I later wrote-that I will follow you suggestion exaclty. My fingers are out of control. My personality prevents me from writing anything rude to anyone, it's a mistake.
I very much appreciate your and other's input thus the reason for becoming part of this forum.
Thanks for everything and, once again, forgive my mistake.

This is usually a good way to do this (except if you do it without replacing the crush washer, you risk leaks). BUT: it sounds like you can start it up, and as the (possibly) clogged fuel filter can't keep up with the injectors, the pressure in the rail drops until the engine quits. But the fuel is still working its way through the fuel filter, and repressurizing the rail, until you're able to start it later.

I'm only guessing (but it's an intelligent guess). So checking that you have pressure "sometime" won't be enough to tell if a clogged filter (or line) is the problem. You need to watch the pressure as it's running, and if it quits with too-low fuel pressure, that points to a clogged filter.

A pressure gauge is not cheap (
this one this one
has the coupler you need), but I can't think of a better way to check.

Above is the best answer but the second best budget way I can think of is to repeat your original method but check the return line not the supply line. There should be pressure on the return side as well. After saying all that you could go one step further and use the diog port and jump the fuel pump and let it run for a few minutes while listing to see if you hear a change in the flow or hear it stop all together. Just a thought for cheap/free info.

That's a good idea. I'd do that first. (You'll have to listen very closely at the regulator; the pump isn't very loud, but it's the loudest thing at that point. If you have a clog, the pump will keep running but you'll hear the flow change through the fpr.)
