If I missed it I apologise, but I see no where that you took the fuel line off the carb, and cranked or run the engine for a quick minute.
it should be squirting fuel with every pulse and a goodly amount, till the carb bowl runs dry and the engine quits ( or you let off the starter if cranking)
I have seen mechanical fuel pumps that had a loose valve in the pump bore and the valve,and or a broken spring just flopped in the worn out plastic housing.
You might have a failing pump.
I'm not one to shotgun parts at a problem but if you are not seeing fuel pulse out of the pump, that could be a problem,
it should pulse like a dog pissing, not an old fart with a prostate problem.

So what i have found is when the engine stalls i take off the line from the fuel pump to the carb and crank usually a little bit of fuel will spit but not much, the i take off the line from the tank to the fuel pump and hold it down to the ground to get fuel flowing reattach when i have a good flow and crank till i have a steady stream of fuel then hook the line back to the carb and it fires up sometimes long enough for me to finish mowing or sometimes i have to repeat the process again

It almost sounds like there is still trash in the tank.

Sounds like you may have a defective fuel pump. To eliminate that as your problem you can remove the hoses from tank and carb. Place the tank hose end in a container of gas and aim the carb hose end away from anything hot or that creates spark and while holding container of gas below pump crank engine over. If pump pulses a good amount of fuel your pump is probably good and you have issues with either tank or carb. Please be very careful around gas and only perform this test outside and away from buildings.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
