Along with checking the plugs and wires, I would also be interesting in what the fuel pressure is doing.
While driving around I noticed the fuel pressure is about 43.5 with dips to 40ish but pretty consistentaround 43.5. I have no idea what the running pressure should be.

43 or so is good, but does it stay that way when it has the issue?
