My 94 XLT will start fine in the morning, but if it's hot (+90 degrees) out, it won't start. Check engine light not coming on before turning the key and don't hear the fuel pump kick on. Also, in the last year, it has taken to just dying while I was driving, everything would shut down and at first it would start back up within 5-10 minutes. Now I'm lucky if it'll start after sitting for a few hours. We've replaced the fuel pump & filter, coil, crankshaft positioning sensor, spark plugs & wires, fuel relay and pulled the computer off of another ranger. Ran fine, no problems for about a 3 weeks. But now it's doing it again. Any suggestions would be appreciated
