When my car has been sitting and cooled down, the engine cranks over quickly and starts right up. However, after it's been driven and is fully warm, when I try to restart it, the engine barely turns over - as if the battery is about to use up the last of its' energy (which it isn't). After several tries with the ignition switch, it will usually catch and start turning over fast enough to start.

Someone once told me that heat transfering to the starter motor while it's running can dramatically reduce the power generated by the motor, expecially if the starter motor is not in good condition. Can anyone verify this or offer any other solutions. I only have 37,000 (original) miles on my car and wonder if that motor could go bad that soon.

I just had this exact same problem fixed in my '64 etype. It was in the carburetors, they need additional adjustment. don't know the specifics,

the first thing to check is the timing, then i would suspect an engine which is getting very hot on heat soak -that is the temporary heat build up when a motor shuts down- it causes very high internal temperatures which can cause the pistons to tighten up in the bores, Jaguar affectionado and etc.
