Truck doesn't want to start

[NeedMoPower]

Just lately my truck has a hard time starting up in this texas heat. It only happens after I have driven it for a while and then try to turn it back on. It keeps turning over, but just won't fire and it only happens in the summer time. I noticed it at the end of last summer, but the problem hasn't reoccured until now. I'm really hopeing that someone has had the same problem or might know what's wrong. I'd really like to get the problem fixed so I won't end up stranded somewhere.

thanks,

cody

My 89 has the same problem. Pulled trailer with tractor 20 miles, dropped off tractor (never turned truck off) got back in truck put it in drive and it went dead. Turns over, cracked injector line 2 and have fuel to injector but it won't even hit partially. Any thoughts??
