Default I spoke too soon!!

I thought I had the issue resolved but today it reared its head again. I started my tractor and it fired right up. I began mowing and after less than 5 minutes the engine stumbled and stalled. As before I twisted the key and it fired right up again but within a few seconds the engine RPMs dropped and stalled. After a couple of tries the engine seemed to stabilize and I tried engaging the mower deck again but a minute later engine dies again. This happened a few more times so I decided to head for the barn. Once in the barn I removed thebside panel and started the engine observing the fuel in the filters level stays constant but the engine keeps stalling. I would think that if it was a fuel starvation issue I would see the fuel levels drop in the filters. I removed the fuel cap to make sure it's not the blocked vent issue again but that didn't help either. The fact that I can restart the engine immediately after it stalls makes me think is not a fuel starvation problem. Correct me if I am wrong.

Next thing I would do check fuel flow at the injector pump and change that short line fuel line.

Have you check the tank exit bungs that has the screens like IHCubCadet147 said?

Finally I believe I found the issue!!
I have always suspected the little electric fuel pump was an issue and after all the messing around I have done I decided to replace it with a low cost Amazon pump that looks very similar to the original!! $21.00 with clamps and fuel line!! Installed with minimal fuss and viola!! Works like new. I guess 30 plus years is a pretty good run for that little pump. Now if it goes again a name brand Kabota pump is about $180.00 and I will go that route.

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.
