Starter relay or no starter relay, Been reading up for an hour and still don't know!! Options

On two occasions recently on pulling onto my driveway after a long journey my car won't restart after turning off to unlock the garage door. Luckily I can then just push the car in but with a European tour booked in the summer I'd like to sort the problem.
When I get back in after opening the garage the lights on the dash dim when I turn the key to start but there is no click. 20 minutes later it will start right up. Is this the problem that will be solved by a hot start relay kit or just a good old fashioned sticky solenoid? I'd rather do just the relay or just replace the solenoid so which is it?
Thanks guys

The first year I drove my 914 I had the problem. Old Timer said clean the contacts. Bought a $10 HF dremmel tool, used the pointy sharp file, and the grinders, and went through all the car grounds. Polished all the wire plugs, buffed the ground straps, etc. they all turned from gray to bright brass. Sprayed electronic cleaner and reassembled. Never had a hot start problem again after 3 years. It's a long weekend of fun, but it works. Adding the relay is probably a workable bandaid. Others also say it takes the stress of of the ignition switch. That's the one reason I'll probably add a relay on my next valve adjustment. (IMG:style_emoticons/default/first.gif)
