A weak fuel pump can cause this problem, but to be sure we can do a fuel pump pressure test which can be done by following this guide:

Pressure 55-60 PSI
Open Throttle - 66 PSI
Has the spider injector been replaced with OEM? Check out the images (below). Please let us know what you find. We are interested to see what it is.
