OK. So I installed a digital voltage meter and had my girls drive it around again. After about an hour it dies again. I hop on it and give it throttle. I can hear the solenoid clicking when I give it throttle and again about 1 second after I let off. The meter says 50.3 dips to about 48.8, goes for maybe 10 yards then stops completely. My foot still fully depressing the throttle, the meter is at 50.3 again. I let off the pedal hear solenoid click off. Press the pedal again and it barely creaps back to the drive way. It will move in reverse though. I let it sit for 30 minutes to cool off and it drives perfect again.
