I just had the same issue with my 88 xlt w/351 W it wound up being the MAP sensor and the timing. I would check both of these and see if it solves your issue.

check the fuel pump relay this sends the power to the fuel pump,

also has the car been in a smash even a small one if so the car may be fit with a enersher switch that cuts off the fuel circuit.

recommend you by a repair manual from your local parts retailer for the exact locations of these 2 units

The only way air can get in the fuel line is if you have a hole in it! Problem of course is were? I would run the fuel line from back to front and back again. Look for any wet spot that you can find. You may even have to drop the tank to ba able to look on top. I would suspect the problem is in the line before the high preasure pump, being as you are pulling air into the system. I have seen leaky lines allow air in, but not let fuel out.
