Thanks Chris for getting back to me. unfortunately I cannot provide an audio or video at this time. I will use an example to explain better.

When for example I begin playing a d chord. I strum it downwards hold the chord then change to for example a g chord. While playing the d the chord sound good and in tune but but I release it to go to the g, I notice that the pitch flattens. This is more noticeable with chords where I have to fret more thinner strings. It's not noticeable with barre chords. Perhaps fretting too hard?. I don't believe so but I will experiment lessoning off my fretting pressure. Action of my electric? I have it adjusted . If I lower it too much, I find that I get string buzz. I will try lowering my action down a bit at a time and see how far I can go. Thanks again. Perhaps another suggestion by you?
