this sounds like a classic Throttle Position sensor issue. I had this similar years back and the dealer had my truck for almost a month and cannot figure out the cause. After finding this solution from dodgeforums, I replaced the TPS myself as they cannot do it if they cannot find the error. Now my truck no longer surges. Could have been a lazy TPS
