HELP HELP !!! Car won't start

[torchmac23]

Hoping to get some help!! I have a 03 mach and it has a fresh build on it roughly about 1500 miles. First day I got the car back from the shop while driving back home the car shut off in the middle of the road. Called the guy from shop and he showed up, when I would try to turn on the car the theft light would blink came to find that pcm fuse was blown replaced it and started back up. A few days later in the morning before work I forgot something inside the house as I came back car was dead and same issue pcm fuse blown out again. So finally about two weeks ago I made it to my drive way and it shut off on me come to find same issue blown fuse. This time I have disconnected the battery replaced the fuse but as soon as I try to turn it on it blows the fuse it cranks but doesn't turn on. I really don't want to call the guy from the shop because I know it will take months before he touches it. And before I take it into ford $$$ I want to get some feedback. Any help is appreciated and sorry if this is not the correct forum.
Thank you in advance!!'
