How to run with pack ME3 multiplayer without dropping?

The title says it all-I have been playing ME3 Multiplayer and cannot carry a picked up item to deliver to LZ without it dropping if I try to run....I cannot remember anywhere in the regular game that explains though it may be there (I've played through a few times) . I have asked other players in multiplayer mode and have gotten no response and have checked and rechecked the written material that the game has within it.... I guess I am missing the obvious. I am tired of costing points lost due to time increased to complete these missions and  want to improve my game and also be a better team (other players have to lose points too they could have earned if they are delivered faster). Any body with correct answer I will greatly be grateful......thanks. wiredwullff.
