need serious help somebody please

I guess you didn't have this problem before? And it runs fine up until the time it dies? It just instantly cuts out?

Do you have a fuel pressure gauge? If you have spark, then it's most likely a fuel issue. Maybe your fuel pump gets hot and can't pump enough...perhaps it's pumping a little, but not enough, so the car dies?

I look at it like this:

If it runs fine and all of the sudden dies out of nowhere, then the timing is most likely fine. Even if it's off a little, I see no reason for it to matter more after 10-15 min. of driving. Additionally, if it runs fine before and has spark when you try to restart, then it doesn't appear to be a spark issue.

All that's left is fuel. You can buy a temporary fuel pressure gauge (not mounted to the fuel rail) at autozone for like $20-25 and test your fuel pressure when it runs fine at start up and then after it dies test it again and compare.

You replaced the TFI module, right?

I had the same problem. After chasing it with a bunch of parts ($$$), it turned out to be the computer.
Run the codes and see what you get. I couldn't get codes which led to swapping the computer.
Good luck!
