Will start and stay running at times, acts like losing spark from start to run, starting fluid does not work replaced crank and cam sensors

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

Sounds like you are pretty knowledgeable with the maintenance. With that said do you know if the Engine Coolant Temperature Sensor (ECTS) has been replaced? I'd put that at the TOP of the list of parts to replace next. If it hasn't been replaced it is the cause of a lot of problems.
The factory one is plastic and cracks. When it cracks it sends the PCM a signal that the engine is -40F below zero. The PCM will compensate by dumping A LOT of fuel into the engine to try and warm it up. It will cause all kinds of starting and idling problems.
Autozone or the dealer sells the better brass tipped one. The ECTS is located just under and behind the upper radiator hose. You'll need to remove the air intake tubing to see it or get to it. It has two wires going to it and goes into a connector. Squeeze the connector at the "ears" and it will come off. A 10MM DEEP well socket will take it out. Swap it quickly because some coolant will come out (a couple of ounces). Hand tighten it and snug it with the socket (not too much because it will strip out). Connector back on (either direction it's non polar). Put the intake back on and enjoy better starting and idling.
Testimonial: "thank you very much. youve been most helpful and i will let you know how it works out for me as soon as i replace the ects"
