Wont start/crank after drivind for a while

[little1]

I have a 6 volt system. Bug runs great and in excellent condition but sometimes when I drive it for a little while and then park it, it wont start or crank over until its been sitting for a while, then it will start or crank over after it has cooled. It has power it just wont crank until cooled.

Does the engine turn over slow and fail to start? Have you already checked all of your grounds? How good is your battery?

It has a new battery, it runs great and purrs like a kitten. It seems that after driving it and it warms up the problem starts. When I get to my destination and park it and try to start it again to leave, it wont turn over. The engine doesnt turn, the starter doesnt turn, it doesnt even make a sound but when I turn the key the lights on the dash and everything turns on so its getting power, all my connections are good. But when I let it sit for an hour or so it will start right up. A few years ago it was doing the same thing and I was told that it was my starter, so I put a new starter on it a few years ago but never really ran it much. In fact after that It sat for around 2 years. Just last month I pulled it out to start driving it again, I took it to a good classic VW shop and went through everything to be ready for the summer. I told them about the problem but it would start right up for them(but like I said it only happens when you run it for a while). It starts right up anytime I want to leave the house but like I said after an hour or so of driving it it wont start until it cools for a while. It gets power but it wont turn.

Sounds like starter is getting hot and won't turn.

Couldn't hurt to check for dirty and loose connections causing a voltage drop to the solenoid, but x2 sounds like a heat soaked starter.

Perhaps a worn starter bushing? Was it replaced when the starter was replaced?

Use your multimeter to check voltage at the starter while a helper turns the key. That should narrow down things a bit.

I believe my starter is getting heat soaked. How can i solve this problem? Is there a heat shield for a 65 beetle starter?
