Porsche Repair: motor stopping, dave thanks, fuel pump

Question
Dave thanks for your quick response
1 25amp

2 On the fuse board its 13th from left to right

3 Yes it turns over almost starts then blows fuse or it starts  if Ihave to wait (cont blowing fuses it can be anything from 5 to 30 mins then may last for months?

4 The motor will crank but will not start (untill fuse is replaced)

Answer
OK...good info thusfar...but I'm still not clear what the 13th fuse does.  Try this site below and click on the fuse charts on the left of that page til you find your car.  I looked and it appears to be the fuel pump and other important things, but at 16 amps, not 25...am I right?
