Voltage variations and Surge cut off.
We are hooked up to 50A service. I just recorded the voltages at different areas and I will note them below. I have a Progressive EMS/Surge suppressor hard wired in just before the breaker box. It has...

I did some measurements this morning again. I think I noted that for some reason the voltage is lower in the morning. But anyway here is what I got:
Voltage at the EMS
Before Both l1 and l2 121 V with 244 across
After the EMS. L1 and L2 121 V with 244V across
The reading on the LED was L1 128 and L2 127
The voltage at the circuit breaker box was 121V on each circuit with 244V across
This leads me to think that the LED display on the EMS is giving false voltages. I do not know if the display has something to do with cutting off the power or not. So I removed it and am still getting all same voltages.
I have a call into Progressive to find out additional information. If the problem occurs next time the heat goes on, ( I tested it and it was OK) then I will switch over to 30A until I get the problem resolved. No problems with 30 A.
