Thank you Printbus. Let me answer your questions first.
Marlin firmware V1.1.0 It has been working with no issues.
Yes, the temp the setpoint inexplicably changes away from the initial 215. That is my issue. I sent a copy of the G-code to Colin and he found no issues there.
I checked the heater and thermister for looseness or shorted wires or loose plugs and did not find anything (that does not mean there isn't any issue there).
The thought of a bad or going bad power supply never occurred to me. I will check that and see if that is the issue. Thinking about that, it would make sense with respect to the symptoms.
I have the wiring zip tied to hold the bundles in place the minimize/prevent movement.
