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

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;

I hope this helps.
