Pickup stalling out

[DeathBy240SX]

I have a 1985 Nissan pickup with 180,000 kms on it. When driving it will sputter out and stall. If I try to start it again it will turn over for a few mintues and then finally all of a sudden start. Or if I wait 30 seconds-1 minute with everything off it will start up again quickly. There seems to be no signs before it stalls except the accelerator will be uneasy. The oil and battery light will come on as it's stalling. It will only stall after a minimum of about 15 minutes of driving. Please help!:help

How's the adjustment on the carb float? You could have a fuel pump that is biting the dust as well. Those old 720's had frame mounted fuel pumps which were exposed to the elements and after a while the wiring would rot right off of them. Check those out for starts.
