1998 Hyundai Excel 4 cyl Two Wheel Drive Manual 150 00 miles

About 3 months ago I did a service on my Hyundai Excel and it has been running fine. I use to drive it everyday, but recently it has started to die on me.

After about 10 min of driving it will suddenly drop revs down to about 1000 rpm and no amount of accelerator will change this. If I allow it to idle for about a minute I can then accelerate and drive for another five minutes before I have to pull over again. Sometimes I can drive for 10 minutes before the problem occurs again. It feel as if the car is been starved of fuel so I replaced the fuel pump but the problem persists. I did change the fuel filter, plugs, air filter, oil filter and oil with my original service 2 months ago. No indication lights come on when this problem occurs. Thanks to everyone for a great site

Hello bliksum check for an intermittent throttle position sensor problem, the signal may not be out of range for the pcm to sett the code. (I'm sending this diagram to your email,it will be more visible.)
