I was driving it all day, and it was a hot day 43+, got home at 5pm, car sat for around 4 hours and I started it up 9pm, started ok, drove 5 minutes down the road, turned her off, tried to start it 10 minutes later and just kept dying. I've had a fuel pump installed 2 weeks ago, regapped spark plugs changed 2 weeks ago. This problem has happened occasionally in previous summers, where it almost died/started shuddering, but dieing 5 times is a joke Coolant temp seemed to be around 35-40%
