89 integra problem...please help ASAP!

Having a persisting problem with my 89' teg. I'll be cruising [doesnt matter what speed, doesnt matter how warmed up car is] and suddenly the car begins to decellerate EXACTLY as if i took my foot off the accelerator, i watch the tach fall and the car die. This whole time, the gas pedal is completely nonresponsive. Electronics still work, just the engine is off [doesnt even help the drop it to neutral; still dies] i have no warning lights of any kind.

My first thought was the cable snapped, but its perfectly intact and works the throttle body just as it should. After this, the car would not start for about a day. I start it the next day, no problemo. anyway, i have the same recurring symptom of the car dying like this, leaving it for a while, coming back, starting up fine, etc. the interval between the symptom is growing smaller, and its happened a total of four times now. i need to fix this.

i am thinking its either a cpu problem or a fuel deliery problem [pump going out? i replaced the fuel filter just to see it it would do anything..] i get spark to the dist. cap just fine when i have a friend try and start it.

any ideas? anyone? HELP!
