1. 1977 Jeep CJ-7 (304 V8)
2. 47,000 miles
3. Stick Shift
4. Strange sounds or smells-None
5. Fluid leaks - none
6. Past repair history Lot’s of UPGRADES

I have a Jeep CJ-7 with a 304 motor. It has a lot of upgrades the major ones being fuel injection and MSD wiring. My problem is: It starts and runs great but I can be cruising down the road at 20, 30 or even 50 MPH and the motor just suddenly dies (doesn’t cough or run rough just loses power completely). I put it in neutral turn the key off and then re-crank the motor. It always starts right up and I continue on. Sometimes it won't do it again for an hour and sometimes it does it over and over.

Thank you for any help,

Do you
have the same problem?

In the fuel system:

The best way to catch this culprit is to hook up a fuel pressure gauge and duplicate the problem could be the fuel pump is failing.

When it dies out also look for spark, disconnect a plugwire and ground it to the engine while cranking engine over do you have spark?
