Couple of questions: does it blow out any black smoke from the exhaust when it starts and have you checked the spark from the coil wire when not starting? First symptom is a fuel problem and the second is a coil problem. Weak coils start fine cold and not so well hot. If you have a strong blue spark when coil is hot it's fine but if weak and yellow probably not so good.
Thanks Coilover. I haven't actually checked the fire out of the coil, but it's only about 3 weeks old. I know that don't mean anything now days with some of these parts we get.
