Bill,
Sounds to me like you've got some sort of crap in the tank itself that
clogging the fuel pickup. After it stops and settles down, the pickup
works fine- until you get going again and bounce the fuel around;
stirring up the mess that then it gets sucked back into the pickup
again; choking out the fuel flow until it just quits. Seen it happen
before on other vehicles. Best bet would be to drain the tanks and see
if you can have them flushed out by a local radiator shop. Any dirt or
rust in them would do what you described. Good luck with it.
