I think you may have an issue with the spider injector. Since the fuel pressure is supposed to rise when you rev the motor. Also take a close look at the cap and rotor (they crack causing issues) Also take a look at the throttle position sensor. there is a chance once the motor warms up and sends the heat that the expansion may cause the reostat (spelling) to expand enough that it wont make contact. And boy do i wish i had your scanner!!! those are sweet.
