I recently bought a 72 F100 from a car dealership in missouri. i towed the truck home and began to work on it. it runs fine except for 2 things.
1. the transmission takes a few seconds to catch and i have to give it a lot of gas for that.
2. the engine starts and stays running, but slowly loses power and then dies. i already checked the alternator and its fine. also has a new battery.

This could all be related. assuming the is an auto trans. A transmission with low vacuum sometimes means the vacuum line to the tranny is leaking or off. It also sounds possible the engine was installed recently, when you say loses "POWER" do you mean as in volts? or engine power? If its engine power and you have a slipping tranny it could be vacuum leaks or incorrectly placed vacuum lines.
POWER= volts. Is the ground hooked up from the intake to the firewall? If there is no ground wire hooked up you will have a multitude of problems with electrical. This is very important to have the ground wire hooked up.
Check all vaccum lines to make sure they are correct and not leaking or broken. Check the fluid level of the trans and make sure its nice and red. Check for a ground wire from the intake to the firewall.

You need a shift modulator to fix the transmission. That is a round object at the end of the tranny, right above the pan. Check to be sure there is a vacuum line attached to it, if not that may be the problem. Check that vacuum line anyway.
For the engine, probably a leaky power valve in the carb. It could be a close point gap, or bad choke/choke pull off, but I'd bet it is a leaky power valve. You will have to remove and re-build the carb.

A lot of times that's just low tranny fluid. If it's full of 120,000 mile old sludge, a flush could work wonders.
Take the air cleaner off the carb and look at the choke plate when you start it. A vacuum powered plunger should crack the plate open as soon as the engine starts, and there should be an electric choke whatsit on the side of the carb that opens it up the rest of the way as the engine warms up.

You might want to check that fluid level in the trans or change the fluid and filter. If this doesn't help, then you might need a rebuild. Check the distributor, mainly the condenser as this is probably causing the engine to die once it warms up. The condenser is a capacitor that lives under the distributor cap and normally should be replaced during a tune up. A better bet is to upgrade the distributor with an electronic one.

you'll have a differt truck.. there should not be a module yet a set of things.. open the distributor.. jog the engine to the timing mark.. whilst on that mark loosen the nut on the distributor.. turn the distributor until the standards are open.. if the standards are no longer open this is the problem regulate them for a niche of 15thousants.. ..next take the twine out of the middle of the distributor.. and place it one quarter inch from the block. turn the engine or open and close the standards you shoul get an arc to the engine block.. after that take a twine off the spark plug every physique and place it so which you will see that an arc from the block.. in case you spot that arc the engine could start up.. additionally look on the distributor cap for shorts additionally verify the rotor for carbon direction or open. ok.. could start up ok.
