Relatively easy way to check a gas line for a pinhole if you have a small vacuum pump. Disconnect the line at both ends and block one end off with a rubber cork or better yet, a threaded fitting. Hook a vacuum pump with gauge to the other end of the line with a valve between the pump and the gauge. Pull a vacuum, close the valve, and come back in a few hours to see if it held vacuum. Often these pinholes can be small enough to not easily show any gas leaking, but sufficient to admit air and create fuel starvation. If you've got a leak or the line is visibly in poor condition, best to just replace it anyway.

Adam's advice on the coil is also excellent, classic symptoms of coil failure are OK at startup and failure as they get hot.
