1998 chevy Suburban 350 vortec

I was thinking it was the anti theft.

But im not to sure. I had an 1995 chevy suburban that I swaped in a 1998 vortec in replaced the dash and columm and all wairing execpt the wire inside that heads toward the rear ac. So its all 98, the front end and commputer is all the 98s. even the frame and gas tank. only thing that is 95 is the body.

The problem im having is that it starts and runs for about 3 to 5 secs then shuts off wont restart tell i turn the key off and turn it back on. then it runs again for about the same amount of time.

Is it the anti-theft?

That sounds like the anti theft. A 98 work truck we had did the exact same thing and we had to replace the ignition switch and ignition harness.

Scan the ecm, it throws a code when the antitheft is bad.
