I do hope I wouldn't be a bother to you all but I actually thought ask questions about my issues on here with high hopes that you all might be able to give me one or three pieces of advise.
My problem is this, I drive a 1989 peterbilt 377 with cummins N14 engine. She starts normally but if I put it off after driving a while, it won't start back immediately unless I allow it to cool for about 30 minutes. Big pain that is!!
I have changed the kick starter and 4 batteries with no difference, she still does same thing, it won't start when hot until I allow it to cool.
Any advice will be highly appreciated as I'm totally lost on this one.
Many thanks in for your replies.

I don't know about an 89 model, but you may check if it has one your temperature switch........

sounds like a relay switch is either bad or you have a short in your switch somewhere causing it to get warm. . If it cranks when hot but won't start it might be fuel filter related.

If the starter is dragging when hot, best check the bushing (worn), commutator is binding...
Do a load test on the starter (amp draw)

Kick starter ? you talking about a motorcycle or a truck?
D.Tibbitt Thanks this. -
You didn't specify if the engine turns over when trying to start. Thats an important piece of info.
If it doesnt turn over your starter is probably dying. Could be the solenoid on the starter too. Either way a new starter assembly is likely in your future.
If it does turn over then something electrical is heat soaking. Worst case the ecm. Best case the fuel solenoid. Less likely is the timing sensor. -
