You may want to consider putting in a UPS to make sure the power is clean and consistent even if just to experiment for a short period of time. We have used injectors in the past (no longer), and they were completely fine for us. Never had a problem.
The other possible problem could be your switch. If you over load a switch, the last device(s) to come up on reboot of the switch might not have enough power to sustain PoE properly. I have had to increase power supplies on a few of my switches (or use an additional switch) in heavy populated PoE scenarios.

Hall Sent: Wednesday, August 31, 2016 8:42 AM To: [email protected] Subject: [WIRELESS-LAN] Do you have POE everywhere? Do you have POE in every location or are there some small locations that still use injectors? If you have some injectors left, I have a few questions. 1. How reliable are they? 2. Are your injectors made by your wireless vendor? 3. Do you have a way to monitor how often your APs reboot? The reason I'm asking is that I just discovered that we have some APs that are rebooting frequently and they are all in locations that still have injectors. I expanded some home-grown code and started graphing AP uptime as well as lwapp/capwap uptime. (Found issues with lwapp/capwap uptime in a few locations as well) -- Todd M.
