might be your fuel pump..i had a friend that had the same problem would cut off like 2 times a day. and it was hard to get it started again,changed the fuel pump and that was it.but you can test it with a fuel pressure gauge..hope you can get it fixed

check the msd external coil if you have one. or bypass the msd and see if it does it to you again.

Appears to be the fuel pump. Usually when they start to go bad they'll shut off once in a while (usually when they get good and warm) but will start back up almost immediately. Perhaps the fuel pump is weak, but your filter is clogged, which would also cause this. Check your fuel filter, and change it for like $8.00 and it will buy you a few months to save up the cash for a new pump. Or if you're rich just replace them both
