Thanks for choosing Just Answer . I'm Wolfgang here to help!!
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.

on your vehicle there a really good chance that the main fuel pump is not working. the reason that the run time for 10 seconds because there is a transfer pump due to the design of the fuel tank you have (saddle type). fuel pressure test is needed to verify the issue. recommendeation is to replace both fuel pumps and the fuel filter lid assy. your vehicle is over 12 yrs old . once the replacement of these parts your Cayenne will run like it did before

anything else?

if not.....
