Fuel Pump problems of the 1998 Mitsubishi Eclipse

I bought my 98 Eclipse, standard, in 2003, not even a year after I had it it died on me on the freeway one day. Turned out it was the speed sensor that got me stranded in the middle of no where. About another 6 months later the found an oil leak on the head gasket that was making me misfire, that was fixed. The car was fine until about 2 months ago when the engine went out on me because apparently the engine oil and coolant were somehow mixing, my hoses were out, so was my water pump, O2 sensor and fuel pump sensor, all at the same time. Well I had major work done everything was put in new, about a month later my driver door handle falls off, that cost me 150 dollars! one month after that, now, my speedometer stops working all of a sudden and 2 weeks later my transmission goes out. Also my clutch is going out. So now I cant drive the car any higher than 5th gear because it throws my gear out!!! since I still owe 6k on the car I have no choice but to fix it. Which is going to end up costing me, in all I've spent and am about to spend, as much as I still owe on the car!.

While driving at any speed and when applying force to accelerator pedal without prior warning, vehicle failed to accelerate, causing loss of all power, and resulting in a near accident. Consumer has contacted dealer, dealer has replaced fuel pump several times, but problem still occurs. Please provide any further details.
