You didn't say, but did you check the polarity? Reversed Hot and Neutral.
Refrigerator and computer may not mind reversed polarity
Refrigerator is a simple motor that is across the line. (not polarity sensitive)
Computer power supply is built ready for European 240VAC at the flip of a built-in switch. (not polarity sensitive)
but stove control panel may. (fan blower voltage is controlled by chopped sine wave output of the opt iso and triac)
The cord is defiantly suspicious. Is it a Factory made cord, with molded ends, or shop made?
I'm guessing the 30A plug is of the Twist-Lock type.
(generator not running) At the generator 30A receptacle, see if the ground and neutral are bonded. They should be...Are they?
(cord Plugged in) At the 20A duplex receptacle receptacle, see if the ground and neutral are bonded. They should be ...Are they?
(cord Unplugged) At the 20A duplex receptacle receptacle, see if the ground and neutral are bonded. They should NOT be...Are they?
(cord Unplugged) At the 20A duplex receptacle end of 50' cord check (U-shaped) ground continuity back to tip of 30A Plug ground.
(cord Unplugged) At the 20A duplex receptacle end of 50' cord check (narrow) Hot continuity back to tip of 30A Plug Hot.
(cord Unplugged) At the 20A duplex receptacle end of 50' cord check (wide) Neutral continuity back to tip of 30A Plug Neutral.
Let's see what this gets us and go from there.
