Really need some help fellas

Alright So I have replaced both fuel pumps and fuel filter. The problem of my truck cutting off and being hard to start kinda stopped. But now it has started happening again. I could be going down the road and the truck will cut of for a split second then start back up by its self. kind of like a jolt. But now it is actually cutting off going down the road when going at slower speeds around 20-35 and sometimes lower. It cuts off randomly in fast food lines and usually will start right back up. But today was the worst. Was trying to get home from work and it cut off after 30 seconds of running. And wouldnt start at all till maybe 15 to 20 mins later. My truck is a 97 f350 with a 460. And on another occasion it cuts off when I would use the heater. So I have been told to check for vaccum leaks. So I sprayed a little carb cleaner around the air hoses and intake and nothing happend. Getting frustrated and just want to drive my truck and enjoy my big block ford!!!

It could be electrical...drawing high amps like heater on with weak connections can make vehicles cut off.....look for loose: ground, connections on coil or distributor

pull off main battery cables and make sure both are corrosion free, low resistance (check on ohms less than 2ohms) along with terminal ends. When connected to the battery, try to twist terminals. There should be no movement. A good simple place to start.

No cat, running true dual exhaust with magnaflows. But I do have a stereo system on the truck that was on there when I bought it a few years back. But I checked my battery and no corrosion and good connection. Could it be my ignition coil?

it first started showing the problem this past summer and consistanly got worse at random times. Just cutting of randomly at low speeds and sometimes cutting off quick but firing back up. but sometimes it would die and take close to half an hour till I can re start it.

this is a link on how to test the coil.... hmmm just very odd symptoms...but coil is a good place to start.... it could be getting "weak" and not all the way bad...
