Getting very frustrated with my 72. I thought it was in good running order. Most the time I am just running little errands around town etc. But twice now when I have gone on a little longer drive. At some point...just when I am enjoying it. The engine just stalls. Kinda acts like I am running out of gas, but I am not. At first I thought it was just the aux tank but last night it happened on both tanks. Not something I want to have happen with my wife and two kids on board...which was the case. It also backfired once...which has never happened. But each time it does it, it eventually starts back up and I make it back home. I want to enjoy the experiance, but there has always been something to sour the occasion. Anyone out there have the same issues...any suggestions. Thanks in advance.
