stalling problem

so my 2003 tdi is fine on the freeway but it seems on hot days when i get off it wants to stall and not start back up right away. the temperature gauge shows that the engine is not overheating. after i let it sit for 5-10 minutes it will start back up. sometimes it will even stall again after it gets going. does anybody have any tips or knowledge they could shed on me, everything is welcome!

Dirty diesel filter?

I would change the relay 109 to start

You need the ECU scanned properly.

If you have access to VCDS I would start there. Based on your symptoms I am going to guess your fuel supply lines going to the IP are possibly loose; I would check for any seepage around your IP, filter, etc.. I have heard of this exact problem before, but right this moment, I can't think of anything else for you to do.

Thanks all. I will try your suggestions.

BTW: It is not leaving any codes when it does this.
