when the motor is cold it will start right up. after letting the truck run for like 5 to 10 mins it stalls out. when trying to restart it it will not start untill u let it sitt for a while. i replaced the distributor cap, rotor, camshaft sensor, computer, and igition coil. im told the fuel pump is fine when tring to resart it everything seems normal it just wont firee untill u let it sit for a while. please help
 
It could be alot of reasons. Loose wires, clogged fuel line, air filter, too low RPMs, and more. Try getting a intake system cleaner in a can from any automotive store and spray it in AFTER the air filter. You will have to rev the motor some when you do this. This will clean your intake system from any deposits. Also get some quality fuel injection cleaner. Usually slick 50 or something that costs more than $20. Check the spark plug wires to make sure they are all connected correctly. See if your MAP sensor works. It is located on the air intake with 3 to 5 wires on it (little black sensor)
 
Really, the problem is that it's a 1994. It sounds like you've spent a lot of money on an old junker. Take it out back and put it out of its misery, like Old Yeller.
 
Ok first we need to find out just what happens when it will not restart.
First we need to see if we have spark.
So when it dies, pull off one of the plug wire and put it into a screw-driver.
Now hold it about 1/4 to 1/2 inch from some metal and have someone crank the truck. Is there spark? If not then the dist is the culprit.
Next see what the fuel pump pressure is.
Turn on the key and see what the pressure is, don't guess find out for shure.
Now start it and let it run until it dies. Now what is the pressure?
Did it go down? If so ( and you should have already) change the fuel filter.
After changing the filter, run a fuel pump pressure again. Did it go up after the filter change???

You didn't say how many miles was on the truck. It can be the pump is weak and time to a change.

Hope this helps.
