Car acts dead after it gets hot...

Dental Dart,
Glad my suggestion worked! I personally struggled with this condition for over a year & got stuck a few times waiting for 15 + mins for everything to "cool off" enough that my car would start to crank again slowly(after ~30 mins it would start "normal"). I SHOULD also finish troubleshooting the cause/replacing the switch but am just enjoying driving it for now. Good Luck.
