I don't what I did, but everything works fine now!
1.  I removed the (2) 30A blade fuses from inverter (INTELI POWER 9100 - model PD9160A).  Both were good and I reinstalled.
2.  I opened up the ATS box (same one as image above - IOTA ITS-30R) and insured all connections were tight.  Nothing loose.  I pused on contacts several times.  Nothing stuck.  Closed box.
3.  I switched generator 30 amp switch off and back on.  It was not tripped.
4.  I plugged in shore power.  Turned on lights and they worked.  Tried AC and all good.  Micro, TV amd all 12V items worked as they should.
5.  I unplugged shore power.  Turned on genny.  Waited a minute.  Turned on AC and it worked fine.  
Everything is back to normal.
What could it have been? 
Thanks for the support!
