I got a 99 eclipse 2.0 dohc I just replcaed the head gasket got a valve job done replaced timing belt water pump thermstat spark plug did a oil change to. Now I can just be driving down the road and all of a sudden the car just dies if I try to start it right away it won't start but it will turn over if I wait about 15 sec and it will start right up again. Any idea on what would because this

The coil may be breaking down under load, due to heat. If you have the turbo engine, I would also replace the Ignition Control Module.

I got new sympton ill be sitting at idle and the rpm move around a little not a lot though

That sounds like the Ignition Control Module (ICM) is breaking down. On most cars, a wire goes from the ICM to the tachometer; therefore, every "missed beat" is reflected on the tach.

Could this possivle be a dirt fuel filter
