Electrical problem
1988 GMC Sierra V8 Two Wheel Drive Manual

My truck will start after trying for a while, runs for about 10-15 seconds, then dies. I have dual tanks and it does the same thing on either tank. I have oil pressure once the engine is started, distributor cap and rotor are not very old and still look new inside. Fuel filter is new.
What could cause this type of problem?
