You have overloaded the generator by plugging in too many appliances at one time. A capacitor has likely blown and someone with electrical knowledge needs to troubleshoot and find the damaged part. Appliances draw high amperage and when they cycle on they draw 50 percent or more amps, so a refrigerator that might draw 1000 amps could jump to 1500 when the compressor cycles on. If two or more appliances cycle on at the same time, they will exceed the capacity of the generator, that is unless you have a very large unit.

Try disconencting the remote start wires between the transfer switch and the generator, if ot still does it you have a bad control board. If it stops, then check the transfer switch for correct wiring of utility and generator power wires, also check with an ohm meter if the run contacts in the transfer switch are closed, that would indicate loss of sensing, or bad board

Check fuel supply, carb etc

Disconnect the control wires and see if it still does it
