Sounds like heat has upped the 'resistance' in all the cars wirering.
This will lead to a reduced amount of current available to get through
the switch. Turning off the ign. and back on again generates a spike,
see were I'm going with this?

Contact cleaner on the switches.
Improved contacts between the Positive & Ground contacts, esp in the
engine bay.
Increased Amperage output Alternator.
Larger gauge wirering in strategic places.
