My  88 C4  Starts ,runs for about 15 mins and then shuts down while driving . There have been a couple of issues I've corrected so far . 1st the Fuel pump relay ,2nd the fuel filter , 3rd I've replaced the fuel pump . All of these parts were original equipment and need to be replaced  ....I had very poor fuel pressure ,After I replaced those items  MAN!!!! it ran better than ever up until the  part where it shut down again Wacko  Now I have no spark , Where should I start  looking  ?

Classic symptoms of a failing Ignition Module, inside the distributor.

Joel ,I'm glad you chimed in on this  ,Your Opinions ( Advice ) are always  solid  & Good Stuff  . I had just hours ago ordered a new  Distributor  W/ Ignition module , Just because that OEM Dist I"m sure has plenty of play in it ( Worn )  @ 180,000 + miles. Now I have another question for you , Is there a Cam Sensor ? or something that triggers the  injectors  to open & close  ?  or anything else that may or may not trigger  Spark that  I've overlooked ?

Spark and injectors fire off of the ignition pulses...no separate cam/crank sensors on the L98.

Ya beat me to it, but my vote was ignition. Same as I described awhile back with my Opti-spark. Hope yours is easier to change.
