EFI Problems

Hello everyone. Here's the deal....1987 F150 5.0 Windsor....Engine shut down,mostly at idle when in drive. Replaced all fuel filters, new distributor, new ignition coil new alternator, new radiator, new hoses, new water pump, new EGR valve, new TFI module ( new wiring harness for TFI module....checked the connection-no hesitation when wiggling it). I am now getting a secondary hesitation while at idle when stopped in drive, and the truck hesitates like it's starving for fuel, just for a second, and either it shuts off, or moves forward, all the while lagging until I get up to speed. Then it cuts out every once in a while when driving at highway speeds. It doesn't shut down at highway speeds like it did before. WHATS THE PROBLEM? It also has new battery (checked the connections there too), new shocks, new upper and lower ball joints, new oil, new oil pan gasket and transmission filter, ran two cans of sea foam with half a tank for each sea foam container to clean the injectors.

Is there someone out there that can help me figure this out? Thanks!
