Getting a couple more MPH by increasing air pressure in tires is a good sign.

Cables and solenoid are possibilities, as are batteries and motor.

Or it could be all of the above. Have to do some troubleshooting to find out.

After running at top speed for a mile or so, are any of the cables more than 10°F above the ambient air temperature? If so, they cables need to be replaced.

Without a doubt, the stock solenoid needs to be replaced.

This is speculation, but the voltage applied to the motor's armature when at top speed is 36V or less. Either the battery pack voltage is dropping to that level, or there is excessive resistance in the high current loop that prevents full battery pack voltage from reaching the armature.
