[Bob Reynolds]

when i hit bumbs at fairely low speeds truck stumbles for a second now the door locks start going up and down several times and the radio screen goes blank 10- 15 seconds

just wondering if anyone out there has had similar experience?

Sounds like a grounding issue. Check the three main ground points, but particularly the body ground as I believe that’s where the BCM gets ground from. Could be too that your neg battery cable is faulty. You Can check resistance of cables.
