problems with my 1992 240sx PLEASE HELP

[justdrift_s13]

i have a 1992 240sx. i has not ran in nearly two years, but the other day me and a friend finnaly found the problem. whoever owned the car b4 i did had spliced the coil wire to hook up a relay for a flamethrower kit. thats what killed my car. we fixed that problem and it was running ok. it had a little miss while ideling however, but the other night when i was driving to work the car just died like i turned the switch off. it got down o about 20 mph and i got it to start again. i made it to work but it died when i pulled in the parking lot. i finnaly got it to crank back but i just left it there and came back to get it the next day. it cranked fine, but as i was on the way home it died just like i had turned the switch off and this time i couldnt get it to crank back. dad pulled it home for me and that night it cranked fine again. for the past two days i have started it and when the engine gets warmed up it dies just as if i had turned the switch off. if i let it sit a little while it will crank and run till it gets hat and do the same thing. has anyone had the same problem? i think it might be the coil or the ignition module but im not for sure could someone please help.

sounds like the fuel pump is going out.replace the fuel filter at the same time.
