I have seen the plunger in oil pump stick. this is more common first thing when u take off with cold oil usually if you shut it off it will sometimes fix. Sometimes there can be a grove in the housing that plunger hangs up on if it keeps acting up you can pull the pump off polish housing to fix it. Have see the spring brake on the plunger. Five minutes should pull the plug from under the truck and drop plunger.
