My van 1997 Plymouth Grand Voyager SE 3.3L, died while driving, speedometer go down suddenly and motor died. I check signals for injectors, crank sensor, Cam sensor, pump gas, and all ok, I replaced the computer (PCM) and the solenoid module transmission and the problem continued. I test the van with park position for more of 30 minutes and don’t fail. Only while driving for 5 miles fail and then wait for a 1 hour and the van works again another 5 miles and so. Is a problem because I don’t know if will turn off on street traffic quiet or on highway traffic heavy. Please give me directions for this problem. Note. My scanner was displayed several codes, initially problems with gear 2 to 3, then Thanks.

Thanks for your attention, Roy, let me say you the presure at moment fail was 45 psi, because I was had connected a presure gauge on gasoline bar injectors. But will review again. Thanks again

The fuel pump is not likely to stop running while driving unless you have a loose connection at a sensor, defective wiring or have an intermittent sensor (Crank Position). Your descrription sounds like an Intermittent sensor as your engine restart after a short cooldown period. A defective fuel pump with usually fail to run when the engine is attempted to be started.

Thanks for your response Johnny, maybe you are rigth respect loose connection and fial for temperature due space air there, because regard of sensor, let me tell you that was connected an osciloscope during fail driving and both sensors crank and cam was ever sending the correct signal (wave form and amplitude), I will review connections in these days. Thanks again.
