i have had this problem for a while now but its getting worse.
i have a 91 GX FWD series 2 and after driving for a while the car randomly stalls and acts as if its run out of fuel and wont re-start unless i flick the ignition on and off a few times, once it starts up again the power light flashes. once car has started doing these problems if its put in reverse it tries to die and cannot be driven.

do i look for another trans or computer?

any help is appreciated
