1996 E350 engine problems
I have a 1996 e350 with a 5.8L engine. The truck has 312,000mi on it. Anyway I was going on a trip the other day and it drove great for 5 hrs then I went to pass a car and it just bogged down and spit and spudered for a min while I was coasting to the side of the road. After that I would get this evertime I excelerated to hard or just trying to go up an incline. I was almost home when it did it everwhere around town. In park it revs up fine but under load it split and boggs down with a small back fire here and there. I tried my uncles snap on tester on it and would not connect to the computer. OBD II connector under the dash would not work and the computer said to connect under hood but I could not find a connector under the hood. My uncle thought maybe a plugged cat? Any ideas on a problem or how to fix the computer connector.

No power to the OBDII connector is often a fuse. There is no other place to connect the scanner to. You really need to get the scanner to talk to it. The scanner's manual should be in the case and has a trouble shooting proceedure in it.
It could be a plugged cat. To check, remove the O2 sensor and install a pressure gauge. Most muffler shops have the necessary gauge. Or, take a rubber mallet and whack the bottom of the cat. If it rattles, its come apart and is likely the problem.
Other than that, fuel pressure, TPS, MAP sensor, etc... should all be checked.
