I have a 81 k5. When I first start it up it starts with no problems but after driving a short distance and turning it off it struggles to start again. Does anybody know why this can be?
 
If its turning over slow it could be heat sink in the start solenoid. Mine gets that way from my headers heating up the starter. I need a heat shield for mine. It could also be the starter going out altogether if its old.
 
If the ignition timing is advanced too much,it can start OK when cold,but be harder to crank after it warms up fully too...if you hear any spark knock or pinging under a load while accelerating it could be that...wont hurt to check it...sometimes when a starter is getting weak it'll crank a cold engine over OK,but when it gets heated up it gets harder to crank,and will give troubles,ditto for a battery thats losing its "beef" when it gets old,they fail under heavy load .
