Other Fuel System Tank Assembly problems of the 2002 Dodge Ram 2500

While accelerating the truck start the decelerate and reaccelerate multiple times within a 2-3 second time period and the check engine light came on for large evap leak. This issue happened a number of times throughout a couple week time period. When I brought it to the dealer they said there was debris in the tank that could have clogged the lines, flushed out the lines and continued on. The issue happened again a couple of weeks later and continued for weeks. I brought it back to the dealer they said the pump was bad and needs to be replace, replaced pump continue on. After about 8 months the issue came back and check engine light came back on for large evap leak. Had system check for leaks and found none. The issue still continue months later a random intervals. Luckily the acceleration issue has been mostly when I was accelerating from low speeds and from stop lights. If I had this issue when trying get a cross a busy intersecting I could be killer.
