Very difficult 'Wake Up' from sleep mode

For the last several weeks my iMac (Retina 5K, 27-inch, Late 2015—Mojave) has been difficult to wake up after it goes into sleep mode. It takes jiggling with the on/off button in the back of the display and pressing on several keys. Sometimes it down't wake up at all and I must restart.

I have run Disk Utility.

Any ideas will be appreciated!

iMac won't "wake up" Why isn't my iMac "waking up" from sleep mode. I'm having to hold the start button to force the iMac to shut down and then restart my iMac... what is going on? Two weeks ago I had Apple replace the disk drive with a new Flash (SSD) drive. It has worked great until yesterday when it wouldn't wake up and now today it wouldn't wake up either and I had to go through the forced shut-down and restart. I now have moved the energy saver to "display never turns off", but I don't like this as a long term solution. Any ideas?

iMac sleep wake failure I have an iMac 2017. After sleep it never wakes up, instead it needs to be powered back on. On wake I see a sleep wake failure popup. A sample of the report it generates is attached. Any ideas?
