Strattons

I hope someone can help. I have a 4 zone system and get the water from a lake. In the past few months I have had issues with the pump loosing its prime. I replaced the check valve at the lake edge and the strainer in the lake. I have replaced the index valve as well.
I have 3 zones that come on as soon as the pump starts, there is a little air blowing for the first minute and then each zone runs OK. One zone always makes the pump drone as air is in the pump. I open the valve and exhaust the air and after a few minutes it will run OK. If I leave the system to run on the timer more often than not this zone is missed as the pressure loss makes the index valve drop and move to the next zone. I have made the troubled zone come on as number 2 or 3 and still have the problem. Zones after it are OK and before it are OK. I don't know what to look for next.
