Sudden Engine Cutout During Warm-up??

Hi there, new to the site here and new Packard owner as of five days ago. I have a question that hopefully someone out there may have experienced before or just have good intuition about. We're now the proud owners of a 1950 Standard Eight. The engine sounds great and turns over generally with a half crank of the starter. Problem is that after about five minutes the engine cuts out as simple as someone turning off the ignition. If you wait a while it will start up again and do the same. If the weather is cooler it will stay running a few minutes longer and opposite if warmer outside. It seems interesting since it doesn't really run long enough to get close to reaching operating temp let alone overheating. Something else may be getting fouled up as it warms up but what could it be? I originally thought it was an electrical issue and the battery seemed a bit sluggish and it's brand new so I rebuilt the generator. That had no effect and I have the same problem. Maybe electrical is barking up the wrong tree? Unless a condenser perhaps? If anyone has a thought I'd really appreciate it. Right now I'm wandering through the woods at night blindfolded on this problem.
