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 
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.
