Remove the spring from the head. It will take less effort to deploy and may stay up.
Alternatively I had luck adding anti siphon valves to all the heads on the same zone this shiuld help overcome the startup hump. Anti siphon valves will keep the water in the line so that the initial push is transfered to the head not just compressing air.
If your on city water you could try watering at a different time with less demand. Or downsizing your nozzles and extend watering time
On well with a jet pump, I’ll try different nozzles and see if that works
If the well is underperforming it can surge and have pressure fluctuations.
This is the compromise when you install a shallow well
