It's a lifter leaking down and you are not running it long enough it hot
enough and log enough for the lifter to pump back up. When this happens
on a regularly driven vehicle - that is, driven at least every third day
or su, - just driving it will pump it back up in just a few miles.
Hardly ever happens on a daily driver.
