Chevy starter issues

[Greg Reimer 7376]

Got a 91 Chevy pickup,350 TBI motor, bunch of miles, still runs pretty great for 290,000 or so miles. Seems that this truck always has had starter issues, replacing it makes the problem go away for a while, has the usual GM Chevy hi torque starter, the problem is that it starts fine first thing in the day, but drive it a distance or on the road, and it has a chronic hot no start condition.Turn the key to Start, not a sound. The gauges move, there is current where needed, but it won't even activate the starter when hot. Let it set a few hours and it's fine until it gets hot again. Starter won't make a sound or do anything when hot. I've put four or five starters in it but I've also had the truck almost 22 years. Other GM cars seem to do the same thing. Any ideas regarding a chronic hot engine no/start?
