Problems, yeah I've got'em

Hi there,
This is my first post so please be gentle.
I have a '96 318i I bought new.
Here's my problem...The car starts fine when the engine is cold. When the engine is warm however, it will not start. The engine will not turn over. I think it's an electrical problem. It'll start if jumped. Once started, it runs fine. I was wondering how I should trouble shoot this and if anyone had an idea what it might be. I have checked the fuses and they're fine.
I appreciate any help I can get.

Thanks...

Could be a couple problems. It is possible that you have a bad pass side motor mount bracket. This bracket supplies the ground from the motor to the chassis. I have seen this problem caused by this. I would check here first. Keep me updated please.

Well, I just found out what was wrong. The starter was dead ar at least trying to die and a fuel line had a leak in it. Yep, this is why I should spend more time under the hood. I had ruled out the starter due to intermittent starting. I thought it would quit and not work again. Well, that is not true. A new starter was about $100 bucks and the fuel line was about $5.00 but my car starts without hesitation...priceless.
