Yes, this has happened to me more times than I want to think about. Would be chasing the tank, stop to heal said tank when there was a short chance, only to have tank decide to run almost immediately again. Only so many instants available before all on cd.
It looks like you're WHM, so you have Bene as an emergency button, and regen/shield to precast on the tank. You should be positioning between pulls, so that you can be there for the next pack.

Especially as WHM dungeon healing centers around starting double pulls with Holy spam for free damage and stunned enemies! You should be at the leading edge of the pack and have less time to run than the tank.

We also have lilies to cast on the go between pulls. Which is perfect for charging our big nuke.
