will not start when hot

[screwballl]

Ok i got the hesitation problem solved, now I would like to hearsome opinions on 2 other subjects:
1) If I go somewhere, turn off the burb, come back it will start then drive somewhere else and turn it off there, it will not start after the second stop. The only suggestion someone had is a heatsheild for the Starter since all the power wires going to it are in good condition. Someone said they have a thermal sensor that will not allow it to work if it is running too hot.
Suggestions or previous experiences?

2) Brakes question, seems at any given time when releasing the brakes from a stop (or slow up), when I release the pedal, I hear what sounds liek one or both rear brakes releasing with a jolt or "bump". Sometimes it doesn't happen until after I touch the gas and start going.
I am having my brakes checked tomorrow (and hopefully getting true dual exhaust too) so hopefully it just needs adjustment or pads, not something serious.
Suggestions or previous experience with this problem?

Both are on same burb, mentioned in my sig below.
