it sounds like a fuel pump .remove the fuel inspection cap on the fuel rail at the top of the engine and make a pump presser check,must be around 45-65 psi, anything lower means a defected pump.another way
of checking a pump is banging on the fuel tank while having some body cranking the eng. if the eng fires up it means it is a pump.
Get a can of Starting fluid from the parts store and spray it into the air intake hose to the engine, if it fires up and stalls right away you have a fuel pressure issue, more than likely a defective electric fuel pump inside the gas tank.
It might be a failing fuel pump, or it could be something like an ignition module. If/when it happens again check for spark and fuel pressure. No fuel pressure is probably a bad fuel pump, no spark could be an ignition module. Those aren't the only possibilities, but likely ones IMO.
Have you replaced the fuel filter (located along the fuel line from the tank, just ahead of the rear wheels)? Also, have you made sure that the fuel pump is properly grounded? Does the fuel gauge work? If you have a loose or bad ground on the tank, neither your fuel gauge nor your fuel pump will work properly.
Replace the distributor's magnetic pickup located inside the distributor surrounding the distributor shaft, the only other thing thankfully on this ignition system if memory serves me on the f 150 straight six 300 cu inch is the dura spark ignition control box, of course do the obvious tune up parts replacement dist.cap rotor,plug , sparkplugs before spending the $40.00 - $50.00 bucks on the dist.. pick up, you may have a weak a fuel pump check for adequate fuel pressure at carb 7 - 10 lbs.
my dad used to say you need two things to start a motor; gas and fire. Check these and make sure they are both good. You have to go through the steps from there. Could be a fuel filter. could be bad plugs. etc. etc... Hope it helps.
