Not sure how I lost prime... but... my pool had about 6" too much water in it (not sure if my auto-fill is leaking or acting up), so I drained to proper level (turned off pump, lever to waste). I turned off pump, lever to filter, and I ignored it. I happen to glance at the pool an hour later and level was down 6". I noticed water slowly pouring from drain in yard (pump not going). I turned pump on and took me 30 minutes to get it to prime (turned pipe to pool halfway off, skimmer off). What's the best/fastest way to get prime? My pump bowl is always drained after the pump shuts off, but it takes less than a minute to prime on a normal start.
