SOURCE: Engine stalls
sounds like one of a couple things could be causing you problems first would be the fuel pump may be wearing out. these are a mechanical pump and should be producing over 35psi at the injection pump if you have a way to put a gauge on it you could check this under full throttle is when you want to watch it though. fuel gauges are quite inexpensive and are handy to have in the truck anyway. another thing i have seen cause this is the check valve on the discharge of the pump there is a spring and ball in the return line banjo fitting that holds the fuel pressure at a constant 35 psi when that gets weak it allows more fuel to return to the tank which will let it run at lower rpm's but not under full load. hope this helps

Does that 94 have the two fuel pumps on it? If it has the fuel pump on the side of the block and the high-pressure fuel pump on the top, I could almost bet that the one on the block has a check valve going out. Seen I guy spend $700.00 on a new pump and injectors and didn't bother to test the delivery pump. If it does have the primary pump on the block and the check valve goes bad when cold it would run fine and when it gets hot it loses it's prime, it's easy to test just pull the fuel pump off the block and plug the fuel line both sides and while you have it out push down on the actuator with your finger on the suction side and one on the pressure side, if the pump fails to hold vacuum for more than a minute replace it. Otherwise it will destroy the pressure fuel pump and that is expensive. As well the shut off solenoid can be taken apart on some of them and on the back side it has a round disk like on a started solenoid remove the two screws that hold them on clean the round disk with sand paper and the to contact points as well if there is a burr sticking out on one of the contacts file it off with a file then sand it down. Some of the fuel shut off's come apart from the front, either way it's a easy thing to check on both and could save you some big money. Also please rate me as I am a mechanic not a typist so it takes me some time to do this, fact is I could of done what I told ya already if I had the truck. Those Cummins engine was the cats meow when they came out.

If you do not refill the filter housing after replacing the fuel filter there is another way to refill the housing.
after the filter is replaced and the cap is secured turn the ignition to run for about 5 seconds then turn to off. again turn to run for about 5 seconds then turn off. Repeat this about 8 to 10 times and then start the engine.
What happens is that every time you turn the ignition to run the fuel pump attempts to pressurize the line then shuts off. That is why you have to repeat the process.
While the truck is running the power to run the fuel pump comes from ecm. Some kind of safety function Dodge has built into the system so fuel will not continue to run if the engine is shut off.

I have 2004 Dodge 3500 w/ 5.9 Cummins , at about 80,000 miles I had excessive oil fumes coming from underneath the hood of the truck . Fumes came from the slobber tube . Took it to the dealership . At first they replaced the fuel rail . Problem got worse . Took it to the dealership again , Oil pan dropped , engine head removed , fuel tank checked , at my cost at first . Results , number one piston top pitted like some took a pick axe to it , parts of piston rings missing , number six piston top clean , but parts of the rings missing as well . This took 17 days for the dealership to find out and to agree to have the engine repaired under warrenty . 14 more days to order and install new engine and turbo . 31 days in total to repair an engine that is defective . Two other engine were in the shop at the same time with the same problem . I now have 100,000 miles on the truck and only 20,000 miles on the new engine with the signs of the oily fumes showing up again . So , rings crack , pieces make their way out of the engine block thru the turbo , back pressure in the crank force the oily fumes out of the slobber tube . That has been one of the problems I have experienced with my Dodge Ram . I am not impressed with my 2004 Dodge , however , my 1995 Dodge Ram was great . Is the new Cummins Engines a true diesel with a replacable cylinder sleeve ?
I hope that this is not your problem , but the fastest way is to check compression in each cylinder and crank case pressure .
