Check the fuel pressure. The fuel pump may be failing.

It has good fuel pressure. I failed to mention that it looses spark when it dies. Would this be an issue with the ignition moduel?

I am going to give you a link to ignition systems. It is a good walk through and has links at the bottom to walk through testing specific parts. You may also search the site yourself to find past Q&A specific to your situation.

Here is the link;
