I have a 99 s10 2.2 it recently started acting up it would loose power and stall as if it wasn't getting fuel and all the dash lights would also start to flash I had it scanned and it said the crank shaft sensor had a problem so I replaced it. It was fixed for about 1,000 miles and it started to repeat the problem again any ideas?

Check the CPS again and also do a fuel pressure check fuel pump could be failing.

Try to duplicate the problem if happens do below to determine what's missing.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil,distributor pick-up coil, ignition control module, cam and crank sensors-
