[Shotimes] SHO shutting down when hot

[Timothy L. Sorrells]

I know I've seen something on this before, but not sure where.

I was told when I bought my car(93 MTX) that when it's hot(outside temp, not
the car) I have to make sure to keep fuel in it or it will die.  Well, it
died on me once when it got to a quarter of a tank. Since then, I've been
keeping at least a half tank in it, but it is still doing it. I was in line
yesterday at the bank, try to take off, it dies.

Funny thing, I thought about vapor lock in the tank, so I open the gas tank,
start it, runs great.

What is going on? Do I need a new fuel pump?

Any help is appreciated!!!
