'95 GT40 occasional hard starting?

Every once in a while my '95, 351W, multiport injection engine will be hard to start. It will fire a couple of times, cough and quit and it will do this many times until I give up and wait ten minutes. It doesn't happen very often but I'm afraid I could get stranded somewhere and it's discomforting. Otherwise it runs great.

Could it be the high pressure fuel pump, or?

Yep
   It seems that over time it gets worse (happens more often) the HP pumps are no longer available for that system. The alternative is to convert to an FCC system like the later models for about $750
I am working on a MUCH cheaper alternative should be able to do some testing next week. I'll report back after testing.

I've owned my '94 Ski Nautique, TBI, since new and had it exclusively in salt water on a buoy or a lift for every summer since flushing it in May and October only. This is the boat I thought I was going to have to ditch the TBI and Protec in favor of a carb and distributor until I determined a faulty oil pressure sender was putting the ECM in Limp Mode which made it vibrate violently at 2800 rpm.

I owned a '92 Sport N for two days only as my wife didn't approve of me spending the winter restoring it.

I've owned my '95 Sport N, GT40 MPI, for about two weeks and it is a keeper as it is nearly in mint condition and requires nothing except solving the occasional difficult to start problem.
