EOS 50D stops taking pictures

[tdpilot]

My EOS 50D stops taking pictures after 4-5 shots.  It seems like the lens stops communicating with the camera.  I can remove the lens, reinstall it, and the same problem persists.  I have cleaned the contacts, no change.  I am using the Canon ES 5, 55-250 zoom.

Thanks, Bob.  I REALLY appreciate your help.  When I get things sorted out and can actually make a determination of what helped/.didn't, I will let you know.

"Wouldn't have thought the grip was that much of a big deal,..."

The reason most 3rd party add-ons are a bad idea is Canon does not document how their cameras work.  So, all these 3rd party companies 'guess' how they work.  Some guess right others not so much.  That makes some of them bad for the camera. Some 3rf party batteries can do unrepairable damage to a camera.  Some grips can also. Some don't have all the operation buttons or few of them. Mostly they are not worth the chance just because they are cheaper which is the single reason people buy them.
