Exclamation Strange Heater Behavior??

I just recently replaced the monovalve in the CD. Once replaced the heat was fantastic and very hot.

Just within the last couple days, it's been acting like a bad monovalve again. I just removed the monovalve about an hour ago and checked it out. No tears, and it seems fine.

I put it back in and went for a test drive and discovered its behavior pattern.

Heat is fine until I come to a stop and then pull away again. Then the heat fades away until it's completely cold. If I turn off the CCU for about 10 seconds and then turn it back on, the heat works perfectly until I come to a stop again.

Any ideas of what the problem is?

I'll be turning the CCU off and on after every stop light until I figure it out.
