Somebody PLEASE help me??!...It might sould crazy though...

2007 Chevy Silverado V6 Single Cab Classic

First off, I am not a vehicle expert, my apologies.

When I start my truck for the first time in the morning it starts up perfectly.
When I turn it off and start it again right away it starts up perfectly.
If I wait 3 hours...
4 hours...
7 hours...Again it starts perfectly.

HOWEVER, if I wait anywhere between 30 minutes to 2 1/2 hours when I turn it off to start it up again....it NEVER STARTS right. It sounds like something doesn't want to "catch". I can let the key go and something sounds like it is "turning" and when the start up finally happens it is extremely "weak", not "strong" like the essential morning start...it barely comes alive. AND IT ONLY HAPPENS WITHIN THAT SPECIFIC 30 MIN TO 2 1/2 TIME FRAME!!!! :screwy: :runaround:

WHAT IS IT? WHAT IS HAPPENING? WHAT IS WRONG WITH IT?? I feel like all the weak, horrible starts are starting to wear down parts! SOMEBODY PLEASE HELP ME OUT!!

THANK YOU.

starter is the first place I would go. do you have an OBD2 reader? if so, what are the codes? But then again, it's a Chevy. Chevy is the only vehicle I ever heard of this happening. This would be the 5th time I heard of this. Replacing the starter only worked twice. Sell it.

My family owns a trucking company and my best bet is its definitely the starter. Get it fix replace and if all else fails.. Sell

Can someone help me fix my grandads 1998 s10, he loves this truck and needs a new door, and transmission. I already got him new tires and I will get him a window. I will also get him new paint for it. Please help me warm his heart with these repairs. https://www.gofundme.com/j7r4stbj
