Any ones thoughts on this issue welcome.  When the temp is below about 72 the ac works great. From about 72 to 82 it will run for 10 to 15 min. and crap out. Over about 82 it is doubtful it runs at all. I checked the gap and it was at top of specs. removed one shim now right in spec. same issues. removed other shim no gap same problem. The clutch attempts to engage spins a little and stops over and over. This leads me to believe the electromagnetic coil is shot and when it gets hot doesn't have the power to engage the clutch??   I found and bought a whole new clutch assembly.  The clutch plate comes right off after that not sure. read some are pressed on others slide right off. In the event it is pressed should I be able to use my gear puller tools to remove it??  Also when putting it back on does it help to heat the coil and freeze the shaft. Any one experience's would be welcome thanks.

you sure the relay isn't dropping out?

It seems to be totally heat generated.  But I will check.  If the relay was dropping out would the clutch still attempt to engage??

Get a set of guages off Amazon.  Sounds like you are low on refrigerant.
