I was driving down the highway recently and my Z just started losing power, spitting and sputtering until it stalled. I was able to get it restarted, but it did it again shortly thereafter. I can occasionally get it re-started, but it doesn't last long. If I keep trying for too long, you can smell raw gas coming out the tail pipe.

Yeah that weird mine 280 turbo does the same thing only It will start doing have promblems well before I take it on the freeway. In fact If I just take It down the street I will start doing that. Some say It my gas tank that Its dirty I say its my automatic tansmission. Because when I drive up hill I start to smoke from the shifter lever then at the end of the hill I will cut out. Let me know if you ever find out what the problem is please.:banghead:
