Do you notice this happens more with a half a tank or less? Is the suction hose inside the tank the original one thats known for collapsing? Thats the first place I would look for the fuel problem. And about the alternator. Maybe the belt is loose and when shifting gears or slowing down, the lower RPMs of the engine is making the alternator not turn as fast and if the belt is loose then the belt will be slipping off the alternator pulley causing the voltage will drop. Do you notice the belt squealing at all? Hope that helps at all. Later, Nick Pitello 1852 <A HREF="Http://members.aol.com/njp548">Http://members.aol.com/njp548</A>
