[Jeep 2.5L TBI Engine Will Not Keep Running]

I really appreciate you getting back with me Moses . This is the first time I turned to the internet for a problem.  It is a 1987 jeep Wrangler with a 2.5L engine. It drives fine for about 20 minutes and the engine loses all power. I will try your suggestions.  Thank you for the reply.

[Jeep 2.5L TBI Engine Will Not Keep Running]

 I've been working on my 1987 YJ Wrangler 2.5L TBI  for sometime now. I put in a new gas pump, gas tank, fuel filter plugs and a distributor cap. Before that I put in a new radiator due to an overheating issue.  When I get out and drive for about 20 minutes it just dies and will not start back up. I let it sit for about 10 minutes and I can get another 20 minute run out of it.  Please help me to get cruising again.
