Found this when I did a search for Kenwood TS-430S.  It discusses the problems your having.

Take a look.

> Hello, 
> I need help with my TS-430S. 
> It receives fine but when I transmit the transmit power starts out at 
> 100 watts with a rapid fluctuation of a few watts, after a second or two 
> the wattage swing gets larger and the power slowly drops to nothing. 
> The Final heat sink gets warm and the fan kicks on. 
> 
> The transmit power stays dead for about 5 minutes, if I key up while the 
> transmit power is dead the S meter acts as if it is transmitting 
> normally and I can hear the relay in the if board click as if it is 
> transmitting normally. No other symptoms are present. 
> So far I have: 
> tested the radio in a different power supply, cable, antenna and tuner. 
> re soldered every connection on the final circuit board. 
> check the ground in the antenna connector. 
> 
> The only parts I have NOT replaced is the IF board, The final assembly, 
> or any parts on the front (switches, display board, ect.) 
> 
> The only reason I haven't replaced the Finals or the IF board is I don't 
> have any available.
