[mustanggt_50]

i experienced a problem like that with my 87 Gt right after i put in the rebuilt motor, i would drive it for maybe 30 min to an hour then it would just stall, and do the same thing that you describes, it would only start back up after letting it sit for a min or two. anywho, i had a lot of stuff tested, they thought it was the tps, fuel filter, they checked the fuel pressure, said it was on the low side but should be ok. so i decided to replace the fuel pump and went to a 155lph, and the car hasnt stalled since. could be the same with yours, even though u did say the fuel pressure was fine, but i just thought i'd tell u about my simular experience.
