OK, me and my Regina 945 again!

My daughter has been complaining that the 945 refuses to start occasionally after a shut down for say gas or a 15 min run into a store.

It of course worked perfectly for me until last night. While driving, it just simply died. I was lucky in that it restarted in a few mins.

I had just swapped my original Regina/Rex coil/amp for my newer one (still 10 yrs old), and the incident occurred. Thought I ruled the coil/amp out, but now after reading the FAQ all fingers point to the coil/amp. Seems odd that they would both die at once to me. Maybe I need to check grounds and immediate connectors to amp/coil.

Most other typical culprits (CPS, MAP, radio suppression & ignition switch) are pretty new. This sympton, reminds me of an ignition switch issue years back on another vehicle. Reading the FAQ and searching still points to the coil/amp.

Could fuel injection relay do this, my experience is they stick one way or the other. Bad CPS, less than 6 mos old though?

Sweet running car when it runs.....

Any thoughts as always are appreciated.
