When it dose not start you need to verify that it has spark.
Throw a spark tester in the car so that you can do that the next time it dose not start.
This way you can elliminate the electrical to the ignition.
This is also when a fuel pressure gauge on the rail comes in handy so that you can see if you have pressure.
good luck you'll find it.

.. Ok relay's have been put in...new fuel pump, filter, strainer and fuel regulator all Brand NEW! Done a pressure test on the dampers 1 & 2 right up there and holding no problem...tested the ohms on the temp sensor just fine..no gas leaks anywhere...Has anyone had this problem?? I am at my wits end with...I appreciate any and all suggestions..

Assuming this is the 86, Get a can of aerosol freezer from radio shack - it is used to look for heat related electrical failures. Wait the 15 or so minutes it takes for the failure to occur, then spray the final stage transistor packs up front on the apron adjacent to the drivers side headlight ( they have a plastic cover over them and two cable runs to them) and try again. They make be getting heat soaked when you turn off, and will not work again until they hit the right temp. If this is not the problem, use the freezer spray on the temp II and other sensors, and see which works. Repeat several times to verify. If it is the final stages, I suspect the heat conducting grease to teh heat sinks on the final stages has dried out and they are getting way to hot.

Next time it acts up, press the gas pedal down and hold it to the floor while turning the engine over. See if it starts then. If you've already tried that, I'm going to assume that it didn't produce a different result.

We had an 85 with a MAF circuit that would fail when hot and shut the car down.
Rich Andrade found it after I got frustrated and boxed-up the brains and MAF and sent it all to him. Not saying its your problem, per se, but it can happen.
Perhaps send him a note to discuss.
