It runs fine at first but after about 10 miles it will die. Restarts then dies again about every mile until I get it home. Runs strong when it runs, no sputtering, etc.
New plugs, wires, rotor, cap and coil with no improvement.

Any help appreciated.

Hi ...I forgot to mention that a dirty fuel filter could easily do this. The car sits and the particles packing the filter loosen up. Then you drive the car and the particles are all sucked into one point and manage to choke the flow through the filter. Replace the filter and when you do, look and see if the gas pouring out of the disconnected filter is like dark beer. If you drive around with a dirty filter you will put strain on the fuel pump and accelerate its demise if its old

This is probobly not going to apply but I had the exact same problem with a 1990 740. It turned out to have two fuel pumps. An idle pump and a high speed pump. The high speed pump was broken so that when I drove at higher speeds the engine would be sipping gas from the idle pump and would run out as the idle pump was not meant to deliver gas at the high rates of highway driving . Letting the car sit gave the idle pump time to refill the lines and begin the cycle all over again.I could get between ten and twenty miles depending on my speed before the idle pump fell behind. I would be surprised if Volvo continued that system into the 94 models
