Losing Power on Steep Inclines

[Andy Ramm <aramm@concentric.net>]

Greetings all, sorry to bother you with this.

Today driving to work in my '67 BGT, the car seemed to lose a lot of power as
it climbed a steep incline, as though one or two cylinders were cutting out
temporarily.  Once the hill was crested, the power gradually came back.  Any
suggestions of what this could be?  Fuel pump?  Floats?

Thanks,

Andy
